IL17F and infection: Similarly, IL-17A levels were high in patients with DM-TB but diminished in patients with newly diagnosed DM and TB comorbidity (Kumaret al., 2020).Kumaret al. (2014) also reported diminished levels of IL-17F in patients with latent TB and DM or pre-DM.Fraser-pittet al. (2023) found that models of MTB with the pathogenic protein MS1987 caused a decrease in levels of 1L-17 in the lungs at day nine post-infection.
