CXCL10 and tuberculosis: Biraro et al. (2016) previously showed that IP-10 performed well in differentiating contacts with either latent or active TB from those who were uninfected in Uganda. Our study corroborates these findings and the potential of IP-10 as a potential biomarker of LTBI (Biraro et al., 2016). IP-10 is secreted from cells stimulated with type I and II IFNs and LPS, and plays an important role in recruiting activated T cells into sites of tissue inflammation (Blauenfeldt et al., 2018). Several studies have shown the potential of IP-10 as biomarker for TB (Yassin et al., 2011).
