CD38 and tuberculosis: Unsupervised clustering further revealed 2 distinct non-classical monocyte subsets associated with disease states: A CD86dim CX3CR1dim CD45RA+ GPR56+ CXCR3+ subset significantly depleted in individuals with CAD, and a CD86+ CX3CR1++ CD45RA++ GPR56- CD38- CXCR3- subset enriched in individuals with latent TB.<h4>Conclusions</h4>These findings underscore the complexity of the monocyte landscape in CAD progression, particularly in regions where HIV and TB are co-endemic.
