About
Michael B. Fessler is a leading immunologist whose research centers on the intersection of lipid metabolism, membrane biology, and innate immunity. His work has fundamentally advanced our understanding of how cholesterol and lipid rafts—specialized membrane microdomains—orchestrate Toll-like receptor (TLR) signaling, the frontline of the body’s defense against infection. A landmark contribution is his proteomic analysis of ABCA1-null macrophages, which identified stomatin-like protein-2 (SLP-2) as a novel regulator of raft composition and TLR signaling. This finding challenged the prevailing dogma that raft protein localization is solely cholesterol-dependent, revealing a more complex, protein-driven mechanism. With over 23 citations on this pivotal study alone, Fessler’s work has reshaped the field, providing critical insights into how membrane organization controls inflammatory responses. His research holds profound implications for understanding diseases where lipid dysregulation and inflammation intersect, such as atherosclerosis and sepsis. Fessler’s innovative use of proteomics to dissect macrophage biology continues to inspire new avenues in immunology and lipid research, making him a key figure for students and researchers exploring the molecular architecture of immune signaling.
