Marcus Kaul, Ph.D. is an associate professor of the UC Riverside School of Medicine Division of Biomedical Sciences.

Prior to joining UCR, Kaul was an associate professor in the department of psychiatry of UC San Diego and the Infectious and Inflammatory Disease Center for the Sanford Burnham Prebys Medical Discovery Institute in La Jolla, Calif.

Kaul completed his education and residency in pharmacology before coming to the United States in 1997 to begin his postdoctoral fellowship in 1997. Since then, he has been working in Southern California as a faculty member and research associate in institutions including the Burnham Institute, UC San Diego, and CSU San Marcos.

He is currently a member in several professional associations, including the Society for Neuroimmune Pharmacology and the American Association of Immunologists.

Research Interests

Kaul is studying the role of lipocalin-2 and cysteinyl leukotrienes in HIV-associated neuronal injury. This research is meant to characterize the apparent role of a small acute phase protein and a lipid mediator in the pathological mechanisms that contribute to HIV-associated neurocognitive disorders and dementia using novel in vivo and in vitro models. This ties into Kaul’s interests in cellular and molecular mechanisms of neurodegenerative diseases linked with host-pathogen interactions.

Kaul is also researching neuroprotection by IFN-beta in AIDS to characterize the neuroprotective effect of IFNβ against toxicity of HIV/gp120 using in vivo and in vitro models.

Kaul’s other major research interests include:

  • The influence of drug abuse on neural plasticity and host-pathogen interactions, in particular HIV-1 infection and associated neuroimmunological pathology and behavioral performance. A recent focus in this context is the potential role of microRNAs and long-non-coding RNAs and the application of next generation sequencing (currently SOLiDTM System).
  • The biology of stem and progenitor cells in particular differentiation and function of neural and immune cell types with particular consideration of chronic inflammatory and degenerative processes, substance abuse and neurocognitive impairment.
