FOXP3 and tuberculosis: Also our study limitations include: a) In this study, only two SNPs of foxp3 gene were studied in patients and controls, but since there is still limited information about the relationship between foxp3 gene and tuberculosis, also with regard to the complexities observed in immune responses, it is recommended that other SNPs of this gene be investigated in patients who these studies are likely to help further clarify the interactions between the pathogen and the host.
