In Vivo Study of THC-induced Immune-genome Changes at Single Cell Solution in HIV-infected Humans
December 4, 2023 updated by: Deepak C. D'Souza, Yale University
In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes.

Detailed Description
In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes.
To test these hypotheses, the investigators propose defining the epigenomic and transcriptomic alterations at single cell resolution in peripheral blood mononuclear cells by administering THC to humans with and without HIV infection.
The THC-associated epigenomic/transcriptomic alterations will be linked to genomic variants to understand the causal effects of THC response in immune cells.

Time Frame: Blood samples will be collected to measure changes in gene expression altered by THC before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.
|
Quantity of each gene is measured via sequence transcriptome, and significant differences of quantified gene pre- and post-THC infusion will be identified as THC-induced gene expression alteration.
|

Time Frame: Blood samples will be collected to measure changes in cytokine profile before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.
|
Cytokine profile will be measured using Luminex Performance Human Cytokine Discovery panel before and after study drug infusion.
The 45 cytokines selected based on their established role in immune functioning are: CCL2/MCP-1, CCL3/MIP-1a, CCL4/MIP-1b, CCL5/RANTES, CCL11/Eotaxin, CCL19/MIP-3b, CCL20/MIP-3a, TNFSF5, CX3CL1/Fractalkine, CXCL1/GROa, CXCL2/GROb, CXCL10/IP-10, EGF, FGF2, FLT3L, G-CSF, GM-CSF, Granzyme B, IFN-a2, IFN-b, IFN-g, IL-1a, IL-1b, IL-1ra, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8/CXCL8, IL-10, IL-12 p70, IL-13, IL-15, IL-17A, IL-17E, IL-33, PD-L1, PDGF-AA, PDGF-AB/BB, TGF-a, TNF-a, TNFSF10, VEGF.

Measure Description |
Time Frame |
---|---|---|
Perceptual Alterations
Time Frame: Perceptual alterations will be measured before study drug infusion and 70, 140, and 300 minutes after study drug infusion.
|
Perceptual alterations will be measured using scales such as the Clinician Administered Dissociative Symptoms Scale (CADSS), a scale consisting of 19 self-report items and 8 clinician-rated items (0 = not at all, 4 = extremely) that we have shown to be sensitive to THC effects.
The scale captures alterations in environmental/time/body perception, feelings of unreality, and memory impairment.
|
Perceptual alterations will be measured before study drug infusion and 70, 140, and 300 minutes after study drug infusion.
|
Cannabis Subjective Effects
Time Frame: Cannabis subjective effects will be measured before study drug infusion and 70, 140, and 300 minutes after study drug infusion.
|
Various feeling states associated with cannabis intoxication will be measured using a self-reported visual analog scale of feeling states ("high", "calm and relaxed", and "tired") associated with cannabis effects.
Subjects will be asked to score the perceived intensity of these feeling states at that moment on a 100 mm line (0 = not at all, 100 = extremely).
These data will be captured to validate that the experiment is relevant to cannabis effects.
|
Cannabis subjective effects will be measured before study drug infusion and 70, 140, and 300 minutes after study drug infusion.
|
Cannabinoid Relevant Molecules
Time Frame: Blood will be collected before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.
|
Blood will be sampled for cannabinoid relevant molecules before and after study drug infusion.
Cannabinoid relevant molecules will include THC and THC-COOH levels.
|
Blood will be collected before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.
|
Change in total immediate recall on the RAVLT.
Time Frame: The RAVLT will be administered prior to study drug administration at approximately 25 minutes after study drug administration.
|
Memory, attention, and executive function will be measured before and after study drug administration using the Rey Auditory Verbal Learning Task (RAVLT).
|
The RAVLT will be administered prior to study drug administration at approximately 25 minutes after study drug administration.
