Figure 1From: Neurocognitive and neuroinflammatory correlates of PDYN and OPRK1 mRNA expression in the anterior cingulate in postmortem brain of HIV-infected subjects There are significant differences in mRNA levels of OPRK1 (A) and PDYN (B) between HIV-negative and HIV-infected individuals in the anterior cingulate. PDYN mRNA levels were lower while OPRK1 were higher in HIV positive subjects.Back to article page
