SYK regulates macrophage MHC-II expression via activation of autophagy in response to oxidized LDL.

abstract：:Breast cancer tissue contains a small population of cells that have the ability to self-renew; these cells are known as cancer stem-like cells (CSCs). We have recently shown that autophagy is essential for the tumorigenicity of these CSCs. Salinomycin (Sal), a K (+) /H (+) ionophore, has recently been shown to be at l...
