WebSingle-cell transcriptomic profiling identified TAM subset-specific and common gene expression changes associated with phagocytosis. We uncover a phagocytic signature that is predominated by oxidative phosphorylation (OXPHOS), ribosomal, and metabolic genes, and this signature correlates with worse clinical outcome in human lung cancer.

WebThe OXPHOS of FAs produces large amounts of ATP and represents an important energy source of M2 macrophages (Malandrino et al. 2015 ). Recent work showed that LPS increases fatty acid synthesis (FAS) in macrophages and promotes inflammation (Posokhova et al. 2008 ). WebSep 5, 2024 · This mechanism, referred to as efferocytosis, uses phagocytes to precisely identify and engulf neighboring apoptotic cells. In doing so, efferocytosis mantains tissue homeostasis that would otherwise be disrupted by normal cellular turnover and exacerbated further when the burden of apoptotic cells becomes elevated due to disease or insult.
