The pulmonary commensal Lactobacillus regulated lung gamma delta T cells to enhance resistance against bacterial infections
This study reveals for the first time that pulmonary commensals can resist bacterial lung infections by regulating gamma delta T cells. Notably, we found that pulmonary commensal bacteria, particularly Lactobacillus plantarum and Lactobacillus murinus, are instrumental in combating bacterial lung infections in an IL-17A-dependent manner.
