Although p38MAPK/MK2/MK3 regulated autophagy by phosphorylation of Beclin-1 at Serine 90 upon starvation in HeLa cells has been described (40), it still remains open whether the regulation of autophagy by p38MAPK/MK2 upon Salmonella infection in MEFs follows the same mechanism. This evidence concerns the gene BECN1 and Salmonella Infections.
