Associate Program Director: Kristine Erlandson, M.D., Associate Professor of Medicine, Division of Infectious Diseases (UC-AMC). Dr. Erlandson investigates the complications of aging during antiretroviral treatment, specifically the mechanisms through which chronic HIV infection and the dysregulated inflammatory response leads to early frailty and physical function decline despite otherwise successful antiretroviral therapy. She has identified strong associations between markers of inflammation and immune activation with frailty. Recent work evaluated the effects of 24 weeks of moderate vs high intensity exercise on physical function, as mediated through changes in biomarkers including those of inflammation (IL-6, TNF-α), immune activation (sCD14, sCD163), and insulin like growth factor (IGF)-1 pathway. Dr. Erlandson is also PI of an R01 grant to investigate the impact of pitavastatin on muscle function and intramuscular fat in people with HIV on antiretroviral therapy and she is developing a new project to investigate the mechanisms of weight gain during treatment with integrase inhibitors.

In recent and ongoing R01 funded research she investigated whether gut microbiota composition of individuals with HIV on antiretroviral therapy is linked with metabolic disease; the extent to which microbiome compositional differences are driven by a loss of bacteria that induce CD4+ T regulatory cells; and the interaction between diet and disease in HIV infected subjects in the US and in Zimbabwe. Under her mentorship, trainees can use 16S rRNA analysis, comparative genomics, and meta-analysis to study microbiome changes with HIV-infection, and the relationships between the gut microbiome, chronic inflammation and susceptibility to HIV infection.

Dr. Palmer studies the effects of HIV infection on systemic and mucosal immunity and interactions between commensal microbiota in the gut and lung and the immune system during antiretroviral therapy. His work has demonstrated that HIV-1 replication impacts T cell function by triggering the overexpression of inhibitory receptors, such as PD-1, that induce T cell exhaustion and that that exhaustion can be reversed, and HIV-1 replication reduced, by PD-1 pathway blockade using HIV-infected humanized mouse models. He serves as the Director of the ACI/ID Flow Cytometry facility and the ClinImmune Clinical Immunology lab also brings with access to state-of-the-art flow cytometric instrumentation. ADEAR trainees will have opportunities for mentored research in the microbiome and mucosal immunity in the gut and the interaction between these mucosal compartments and how they influence one another during HIV treatment and in high-risk men who have sex with men.
