LAMP1 and diabetes mellitus: They found a negative correlation between the number of NK cells in DM‐TB patients and fasting blood glucose (FBG) levels.[58] The number of NK cells decreased significantly with increasing FBG levels, suggesting an inhibitory effect of high blood glucose on NK cells.[58] Similarly, another study found that the expression frequency of lysosome‐associated membrane protein 1 (CD107a) in NK cells from DM‐TB patients was significantly decreased.
