Ayan Mondal, PhD

Stanford University


Dr. Mondal is a post-doctoral research fellow in Prof Elizabeth Mellins’ laboratory at Dept of pediatrics, Stanford University. He completed my graduation in Microbiology from University of Calcutta, India, in 2017. He has studied novel virulence factors from pathogenic bacteria and the pathways they use to affect host cells and became well-trained in analysis of disease pathogenesis in mouse models and in in vitro systems, as well as neuroimmune signaling mechanisms in the gut-liver-brain axes in mouse models of a metabolic disorder (NAFLD/NASH) and military-deployment associated disorders (Gulf War syndrome.

His studies elucidated mechanisms of neuroinflammation and blood-brain barrier (BBB) dysfunction that can lead to comorbid symptoms using mouse brain histology and cultured brain endothelial cells as a simplified model of BBB. His work focuses on elucidating the mechanisms of action of novel modulators of BBB that are relevant to homeostatic maintenance of the BBB and other novel modulators that increase BBB permeability during flares of PANS. His proposed experimental strategies include transcriptomic and proteomic approaches in cell types of the CNS neurovascular unit.

BRAIN Funded Projects

Functional activities of plasma from autism on blood-brain barrier; Comparison with healthy controls and PANS

Aims of the study: Investigate the integrity of the blood brain barrier in autism vs PANS by looking at brain endothelial cells monolayer and multicellular systems.
