HSP90B2P and tuberculosis: The remaining small subcluster of neutrophils, marked by high expression of heat-shock protein genes (HSP neutrophils), was also elevated in TB-diseased lungs, which is notable given that heat-shock protein expression by neutrophils can trigger pro-inflammatory response in macrophages (Kauffman et al., 2018; Zheng et al., 2004) (Fig. S2, A–E).
