Dinesh Chandra et al.
Clinical and experimental immunology, 154(2), 224-234 (2008-09-10)
The failure of Leishmania, an intracellular pathogen, to stimulate a pro-inflammatory response following entry into macrophages has been well reported. This occurs in spite of the fact that ligands for the toll-like receptors (TLR) have been recently shown on the
Hanlin Zhang et al.
Molecular cell, 76(1), 110-125 (2019-09-03)
Failure to make adaptive immune responses is a hallmark of aging. Reduced B cell function leads to poor vaccination efficacy and a high prevalence of infections in the elderly. Here we show that reduced autophagy is a central molecular mechanism
