Cellular membranes of peritoneal macrophages

Peritoneal macrophages are a specialized population of tissue-resident immune cells located within the peritoneal cavity, serving as the primary line of defense against abdominal infections and maintaining serosal homeostasis (Ghosn et al., 2010, PMID: 20124434). The cellular membrane of these macrophages is a dynamic lipid bilayer that houses a diverse array of functional proteins, including Toll-like receptors (TLRs), scavenger receptors, and integrins, which facilitate the detection and clearance of pathogens and apoptotic cells (Okabe & Medzhitov, 2014, PMID: 24630722). While the membrane itself is not a single molecular target, it serves as the critical interface for drug interactions and contains numerous specific receptors involved in inflammatory and infectious diseases. Pharmacological modulation of these membrane-associated proteins allows for the control of macrophage polarization and phagocytic activity, which is highly relevant in conditions such as peritonitis, endometriosis, and peritoneal carcinomatosis. Furthermore, recent bioengineering strategies have utilized these membranes to coat nanoparticles, leveraging their natural surface proteins to evade immune clearance and improve targeted drug delivery (Zhang et al., 2017, PMID: 28106391).
