Examples

Materials and Methods

Cell Lines

HeLa human cervical cancer cells were obtained from American Type Tissue Culture (ATCC: Manassas, VA) and grown under fully humidified 5% CO2 environment with MEM supplemented with 10% FBS, 2% sodium pyruvate, non-essential amino acids (2 mM), penicillin (100 units/ml), streptomycin (100 µg/ml), and glutamine (4 mM) (Gibco-BRL).  Cells were passaged by trypsinization twice weekly or as needed based on 75% confluency.

PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMC)

PBMC were isolated from buffy coats by density-gradient centrifugation. Specifically, buffy coat cells were dispensed over five 50 ml falcon tubes, phosphate-buffered saline (PBS)/2% fetal calf serum (FCS) solution was added to reach a volume of 20 ml and 10 ml Ficoll-Paque® was gently added under the diluted buffy coat cells. Centrifugation was performed at 400 g for 20 min at room temperature (RT) and washing of PBMC was done three times with PBS/2% FCS. Culture of freshly isolated PBMC was performed in complete MEM media.

CELL TREATMENTS AND ANALYSIS

ACTIVEIMMUNE was diluted in complete MEM media prepared as described above.  Dilutions of 1:10, 1:100, 1;1000 and 1:10,000 were performed.  Negative controls were complete MEM media.  Positive controls were concanavalin A at a concentration of 2.5 ug/ml.  PBMC were plated at 1·5×10⁶ cells/ml in flat-bottom 96-well culture plates in a volume of 200 µl per well and incubated at 37° in a humidified 5% CO₂ atmosphere.  Conditioned media was then evaluated for IFN-gamma production using ELISA from R & D Systems (Quantikine ELISA).  Concentration was calculated by plotting against a standard curve generated with control cytokine.

HeLa cells were plated at a concentration of 10,000 cells per well in flat bottom plates and incubated with dilutions of ACTIVEIMMUNE at 1:10, 1:100, 1;1000 and 1:10,000.    The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was performed for assessment of proliferation.  In this assay soluble MTT is metabolized by mitochondrial enzyme activity of viable tumor cells, into an insoluble colored formazan product. Subsequently formazan were dissolved in DMSO and measured spectrophotometrically at 540 nm. Briefly, 200 μl of cell suspension  was seeded in 96-well microplates and incubated for 48 h (37°C, 5% CO₂ air humidified).

To evaluate cell survival, 20 μl of MTT solution (5 mg/ml in PBS) was added to each well and incubated for 3 h. Then gently 150 μl of old medium containing MTT was replaced by DMSO and pipetted to dissolve any formed formazan crystals. Absorbance was then determined at 540 nm by enzyme-linked immunosorbent assay (ELISA) plate reader. Each extract concentration was assayed in 4 wells and repeated 3-times.

ELISA

IFN-gamma, IL-4, IL-10 and IL-12 were assessed by ELISA (R and D Systems) utilizing supernatant from mitogen activated cultures and treated DC.

Dendritic Cells

DC were generated from PBMC resuspended in RPMI-10% FCS, and allowed to adhere to 6-well plates (Costar Corp., Cambridge, MA). After 2 h incubation at 37  Celsius, the nonadherent cells were removed and the adherent cells washed in phosphate buffered saline (PBS), followed by detachment by incubation with Mg 2+ and Ca 2+ free PBS containing 0.5 mM EDTA at 37 Celsius. The adherent fraction was subsequently cultured at 3 x 10(6)/ml in RPMI-10% FCS supplemented with 50 ng/ml GM-CSF and 1,000 U/ml IL-4. Media is changed every 2 days for a total of 8 days culture.  DC were  isolated by positive selection for CD83 and subsequently treated with ACTIVEIMMUNE on day 6 of culture.  Assessment of maturation was performed by flow cytometry for CD80 and CD86 expression.

Blockade of TLR-4 was performed using by culture in the presence of TLR4 antagonist LPS-RS (Invivogen (San Diego, CA), (5μg/mL), with pretreatment 4 hours before exposure to ACTIVEIMMUNE.

Results

ACTIVEIMMUNE Does Not Modulate Cellular Proliferation

ACTIVEIMMUNE has been reported to possess anticancer activity.  Accordingly, we conducted a series of experiments assessing ability of various concentrations of ACTIVEIMMUNE to inhibit proliferation of HeLa cells. We utilized the chemotherapeutic drug doxorubicin as a control. As seen in Figure 1a, various doses of ACTIVEIMMUNE did not affect proliferation of HeLa cells as assessed in the MTT assay after 48 hours of culture.  Importantly , supraphysiological doses of ACTIVEIMMUNE, as high as 1:10 diluted volume by volume in the tissue culture media did not result in inhibition of proliferation.  These data suggest that ACTIVEIMMUNE does not act through cytotoxic or cytostatic mechanisms.  These data were confirmed with other cell lines such as PC-3, DU-145, and non-malignant 3T3 fibroblasts (Figure 1b-d).

Figure 1: ACTIVEIMMUNE Does Not Alter Proliferation of Cancer Cells

ACTIVEIMMUNE Acts as a Cofactor for Cytokine Secretion from Immune Cells found in Peripheral Blood

To assess whether ACTIVEIMMUNE directly activates T cell production of cytokines, or whether it requires a costimulatory signal, such as concanavalin A (ConA), was examined.  ACTIVEIMMUNE did not affect viability of PBMC (data not shown). It appears that ACTIVEIMMUNE complements existing production of immune stimulatory molecules after a primary stimuli, but does not initiate immunity, at least based on IFN-gamma and IL-4 production (Figure 2a and 2b).  Given that different doses of ACTIVEIMMUNE possess different costimulatory profiles for the different cytokines, we questioned whether the effect was specific to conconavalin A stimulation, or whether other factors may be at play.  Accordingly, we substitute stimulation by conconavalin A to stimulation by phytohemagglutinin, a mitogen often used in studies stimulating human T cells.  As seen in Figures 2c and 2d, a similar pattern of IFN-gamma and IL-4 costimulation was observed with PHA acting as the primary stimulator.

Figure 2: ACTIVEIMMUNE Acts as a Costimulator of Lymphocyte Activation

 ACTIVEIMMUNE Induces Dendritic Cell Maturation in a TLR4 Dependent Manner

Given the contamination of antigen presenting cells in PBMC, and the fact that antigen presenting cells may be sending costimulatory signals to the T cells in response to ACTIVEIMMUNE treatment, a series of experiments were conducted to assess whether ACTIVEIMMUNE acts on the most potent antigen presenting cell, the dendritic cell.  Day 6 immature DC generated from monocytes by IL4 and GM-CSF treatment were used to assess maturation-inducing potential of ACTIVEIMMUNE.  Cells were treated with saline, lps positive control, and 3 concentrations of ACTIVEIMMUNE.  Additionally, blockade of TLR4 signalling was performed by cotreatment with LPS-RS, an antagonist of the TLR-4 receptor.  As seen in Figure 3a and 3b, ACTIVEIMMUNE was capable of upregulating expression of IL-12 and IL-10, respectively, suggesting from a functional perspective that DC activation was occurring.  Indeed the fact that IL-12 drives Th1 cytokine production and IL-10 drives Th2, these data are in agreement with the previous data suggesting that ACTIVEIMMUNE is capable of modulating immunity.  Definative evidence of maturation of DC was observed using flow cytometry, demonstrating that uprgulation of CD80 and CD86 was occurring as a result of ACTIVEIMMUNE treatment (Figures 3c and 3d).  In all experiments, blockade of TLR-4 by treatment with LPS-RS, an antagonist of TLR4, resulted in marked reduction of both LPS induced changes (positive control) as well as in activity of ACTIVEIMMUNE.

Molecular Characterization of ACTIVEIMMUNE

Two Dimensional Gel Electrophoresis

Two-dimensional electrophoresis was performed according to the carrier ampholine method of isoelectric focusing (O’Farrell, P.H., J. Biol. Chem. 250: 4007-4021, 1975, Burgess-Cassler, A., Johansen, J., Santek, D., Ide J., and Kendrick N., Clin. Chem. 35: 2297, 1989) by Kendrick Labs, Inc. (Madison, WI) as follows: Isoelectric focusing was carried out in a glass tube of inner diameter 2.3 mm using 2% pH 3-10 isodalt Servalytes (Serva, Heidelberg, Germany) for 9600 volt-hrs. One µg of an IEF internal standard, tropomyosin, was added to the sample.  This protein migrates as a doublet with lower polypeptide spot of MW 33,000 and pI 5.2. The enclosed tube gel pH gradient plot for this set of Servalytes was determined with a surface pH electrode.

For the 10% acrylamide gels, after equilibration for 10 min in Buffer ‘O’ (10% glycerol, 50 mM dithiothreitol, 2.3% SDS and 0.0625 M tris, pH 6.8), each tube gel was sealed to the top of a stacking gel that overlaid a 10% acrylamide slab gel (0.75 mm thick).  SDS slab gel electrophoresis was carried out for about 4 hrs at 15 mA/gel. The following proteins (Sigma Chemical Co., St. Louis, MO and EMD Millipore, Billerica, MA) were used as molecular weight standards: myosin (220,000), phosphorylase A (94,000), catalase (60,000), actin (43,000), carbonic anhydrase (29,000) and lysozyme (14,000).  These standards appear along the basic edge of the silver-stained(Oakley, B.R., Kirsch, D.R. and Moris, N.R. Anal. Biochem. 105:361-363, 1980) 10% acrylamide slab gel. The gel was dried between sheets of cellophane with the acid edge to the left.

After equilibration for 15 min in Buffer “O” (10% glycerol, 50 mM dithiothreitol, 2.3% SDS and 0.0625 M tris, pH 6.8) each tube gel was sealed to the top of 10% acrylamide spacer gels which are on the top of 16.5% acrylamide peptide slab gels (Shagger, H. and Jagow, G. Anal. Biochem. 166: 368, 1987) (0.75 mm thick).  SDS slab gel electrophoresis was started at 15 mamp/gel for the first four hours and then carried out overnight at 12 mamp/gel as for the separation of peptides.  The slab gel electrophoresis was stopped after the bromophenol blue dye front had just started running off the gel. The following proteins (Sigma Chemical Co., St. Louis, MO and EMD Millipore, Billerica, MA) were added as molecular weight markers: phosphorylase A (94,000), catalase (60,000), actin (43,000) and lysozyme (14,000).  These standards appear as bands on the basic edge of the silver stained (Oakley, B.R., Kirsch, D.R. and Moris, N.R. Anal. Biochem. 105:361-363, 1980) 16.5% acrylamide slab gel. Low molecular weight markers from Sigma Chemical were also loaded  myoglobin (polypetide backbone) 1-153 16,950; Myoglobin (I+II, 1-131) 14,440; myoglobin (I+III, 56-153) 10,600; Myoglobin (I, 56-131) 8,160; myoglobin (II 1-55) 6,210; Glucagon 3,480; and Myoglobin (III, 132-153) 2,510.   The gel was silver-stained and dried between sheets of cellophane paper with the acid edge to the left.

Proteomic Analysis/Sequencing

Protein digestion and peptide extraction. Proteins that were separated by SDS-PAGE/2D-PAGE and stained by Coomassie dye were excised, washed and the proteins from the gel were treated according to published protocols [157-159]. Briefly, the gel pieces were washed in high purity, high performance liquid chromatography HPLC grade water, dehydrated and cut into small pieces and destained by incubating in 50 mM ammonium bicarbonate, 50 mM ammonium bicarbonate/50% acetonitrile, and 100% acetonitrile under moderate shaking, followed by drying in a speed-vac concentrator. The gel bands were then rehydrated with 50 mM ammonium bicarbonate. The procedure was repeated twice. The gel bands were then rehydrated in 50 mM ammonium bicarbonate containing 10 mM DTT and incubated at 56^oC for 45 minutes. The DTT solution was then replaced by 50 mM ammonium bicarbonate containing 100 mM Iodoacetamide for 45 minutes in the dark, with occasional vortexing. The gel pieces were then re-incubated in 50 mM ammonium bicarbonate/50% acetonitrile, and 100% acetonitrile under moderate shaking, followed by drying in speed-vac concentrator. The dry gel pieces were then rehydrated using 50 mM ammonium bicarbonate containing 10 ng/L trypsin and incubated overnight at 37^oC under low shaking. The resulting peptides were extracted twice with 5% formic acid/50 mM ammonium bicarbonate/50% acetonitrile and once with 100% acetonitrile under moderate shaking. Peptide mixture was then dried in a speed-vac, solubilized in 20L of 0.1% formic acid/2% acetonitrile.

LC-MS/MS. The peptides mixture was analyzed by reversed phase liquid chromatography (LC) and MS (LC-MS/MS) using a NanoAcuity UPLC (Micromass/Waters, Milford, MA) coupled to a Q-TOF Ultima API MS (Micromass/Waters, Milford, MA), according to published procedures [157, 160-162]. Briefly, the peptides were loaded onto a 100 m x 10 mm NanoAquity BEH130 C18 1.7 m UPLC column (Waters, Milford, MA) and eluted over a 150 minute gradient of 2-80% organic solvent (ACN containing 0.1% FA) at a flow rate of 400 nL/min. The aqueous solvent was 0.1% FA in HPLC water. The column was coupled to a Picotip Emitter Silicatip nano-electrospray needle (New Objective, Woburn, MA). MS data acquisition involved survey MS scans and automatic data dependent analysis (DDA) of the top three ions with the highest intensity ions with the charge of 2+, 3+ or 4+ ions. The MS/MS was triggered when the MS signal intensity exceeded 10 counts/second. In survey MS scans, the three most intense peaks were selected for collision-induced dissociation (CID) and fragmented until the total MS/MS ion counts reached 10,000 or for up to 6 seconds each. The entire procedure used was previously described [157, 160, 161]. Calibration was performed for both precursor and product ions using 1 pmol GluFib (Glu1-Fibrinopeptide B) standard peptide with the sequence EGVNDNEEGFFSAR and the monoisotopic doubly-charged peak with m/z of 785.84.

Data processing and protein identification. The raw data were processed using ProteinLynx Global Server (PLGS, version 2.4) software as previously described [160]. The following parameters were used: background subtraction of polynomial order 5 adaptive with a threshold of 30%, two smoothings with a window of three channels in Savitzky-Golay mode and centroid calculation of top 80% of peaks based on a minimum peak width of 4 channels at half height. The resulting pkl files were submitted for database search and protein identification to the public Mascot database search (www.matrixscience.com, Matrix Science, London, UK) using the following parameters: databases from NCBI (all organisms, human proteis and rodent proteins for targeted identification of proteins), parent mass error of 1.3 Da, product ion error of 0.8 Da, enzyme used: trypsin, one missed cleavage, propionamide as cysteine fixed modification and Methionine oxidized as variable modification. To identify the false negative results, we used additional parameters such as different databases or organisms, a narrower error window for the parent mass error (1.2 and then 0.2 Da) and for the product ion error (0.6 Da), and up to two missed cleavage sites for trypsin. In addition, the pkl files were also searched against in-house PLGS database version 2.4 (www.waters.com) using searching parameters similar to the ones used for Mascot search. The Mascot and PLGS database search provided a list of proteins for each gel band. To eliminate false positive results, for the proteins identified by either one peptide or a mascot score lower than 25, we verified the MS/MS spectra that led to identification of a protein. The protein identified comprised of the amino acids:

ACTIVEIMMUNE Activated DC are Superior to LPS Activated DC in Suppressing B16 Melanoma

Mouse dendritic cells were generated by 6 day culture of bone marrow mononuclear cells in IL-4 and GM-CSF as previously described by us [163].  At day 6 DC were stimulated to mature by administration of 5 ug/ml LPS and 100 ng of TNF-alpha as a positive control.  In the experimental group DC were treated with leukocyte extract (LE), which was ACTIVEIMMUNE (ImmunoActive^TM) obtained from Argo Farma, Mexico, was added to dendritic cells at a concentration of 10 micrograms per ml.  C57/BL6 mice were inoculated with 500,000 B16 melanoma cells subcutaneously and tumors were allowed to grow for 7 days.  Dendritic cells (positive and experimental controls) or saline were administered subcutaneously to animals at a concentration of 1 million cells per animal in a volume of 200 microliters.  As seen in Figure 6, a significant reduction in tumor size was observed in mice receiving DC that were pretreated with leukocyte extract.  Tumor reduction efficacy was dependent on NK activity (8 mice per group).  The experiment was repeated however NK cells were depleted by administration of injections every 3 days of anti-NK1.1 (PK136 mouse IgG2, hybridoma HB191; ATCC) (200 μg/dose) antibody intraperitoneally after administration of tumors.  As seen in Figure 7, antitumor efficacy was diminished upon the loss of NK cells.

Augmentation of Natural Killer Cell Activity and Induction of Cytotoxic Immunity Using Leukocyte Lysate Activated Allogeneic Dendritic Cells: StemVacs™
Application No.: 63/045863
Stimulation of immunity would be beneficial in various chronic conditions such as viral infections and neoplasia. Autologous dendritic cell therapy has been widely described in the immunotherapy literature and has been approved by the FDA for treatment of prostate cancer. Unfortunately, the need to generate individual doses is costly and limited by ability of the patients to have sufficient starting cell numbers available to generate sufficient dendritic cells. Here we describe the process of preparing allogeneic dendritic cells utilizing a leukocyte lysate based approach. These data support development of StemVacs for conditions that would benefit from NK activation such as cancer and COVID-19.
