Research Interest
lmmunoregulatory mechanisms can influence many aspects of the body's immune responses to different antigens, and can control inflammatory responses, thereby preventing pathology caused by persistent immune activation and inflammation. The Macatangay laboratory focuses on various immunoregulatory pathways in different inflammatory states, especially in HIV infection. Specifically, the lab aims to define the role of different immunoregulatory mechanisms in: the inflammatory state associated with chronic HIV infection; HIV persistence; and various HIV immunotherapeutic strategies, such as in therapeutic vaccination. By using specimens obtained from the various studies at the Pittsburgh Treatment and Evaluation Unit (PTEU), the AIDS Clinical Trials Group (ACTG), and the Multicenter AIDS Cohort Study/Women's Interagency HIV Study (MACS/WIHS Combined Cohort Study), the lab assesses the immunophenotype and frequencies of regulatory immune cell subsets. It also analyzes specific suppressive function and components of regulatory pathways to further understand the influence of specific immunoregulatory mechanisms in HIV pathogenesis and persistence. In doing so, Dr. Macatangay aims to improve existing or develop new immunotherapeutic strategies for the control of chronic HIV-associated inflammation and/or for the functional cure of HIV.
Clinical Interest
Dr. Macatangay is an infectious diseases physician who rounds on the General Infectious Diseases Consult Service at UPMC Presbyterian-Montefiore. He also has privileges at Magee Women’s Hospital and UPMC Mercy. Apart from HIV and general infectious diseases, he is interested and has done research in parasitic diseases, specifically, helminthic infections.
Educational Interest
Dr. Macatangay mentors medical students, Internal Medicine residents, and Infectious Diseases Fellows in HIV immunology and parasitology research. He gives lectures on HIV Immunology, HIV Microbiology, Sexually Transmitted Infections, and Helminthic infections to first year medical students, and is a problem-based learning facilitator for Medical Microbiology. He coordinates the Tropical Medicine and Parasitology course for the Internal Medicine Global Health Track residents at UPMC Presbyterian, and provides the Helminthic Infections and HIV Immunology lectures to ID Fellows. He also lectures on the Diagnosis, Treatment, and Prevention of Helminthic Infections to MPH students at the Graduate School of Public Health.
