Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO)


The Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) is the coordinating center for the National Institute on Drug Abuse (NIDA) U01 cohorts. C3PNO manages and stimulates the use of the NIDA longitudinal cohorts and addresses high priority research on HIV/AIDS in the context of substance misuse. The emphasis is on cross-cohort research on the 10 North American cohorts enabled by building a virtual data repository, managing a scientific submission and review process, and driving new scientific directions. Funder: National Institute on Drug Abuse

Grant: NIH/NIDA 1 U24DA044554(Gorbach and Siminski)

mSTUDY – Minority Men Who have Sex With Men Cohort at UCLA Linking Infections Noting Effects

[09/30/2013 – 05/31/2018]

The mSTUDY is a NIDA funded research platform to understand the dynamics of substance use on HIV transmission and evolution in a large cohort of men of color who have sex with men (MMSM) entitled “MASCULINE: MMSM And Substances Cohort at UCLA Linking Infections Noting Effects”.  This includes a broad portfolio of inter-disciplinary work from immunology and basic science to epidemiology, prevention and treatment.  It enables important tests of biological influences of substances on immune function to investigate the links between non-injection substance abuse and HIV among Latino and African American men who have sex with men. It maintains a biorepository of specimens for the cohort to be used to stimulate related research.  Funder: National Institute on Drug Abuse

Grant: NIDA U01DA036267 (Gorbach and Shoptaw).
