Deficiency of salt-inducible kinase 2 (SIK2) promotes immune injury by inhibiting the maturation of lymphocytes.

ABSTRACT: Salt-inducible kinase 2 (SIK2) belongs to the serine/threonine protein kinases of the AMPK/SNF1 family, which has important roles in cell cycle, tumor, melanogenesis, neuronal damage repair and apoptosis. Recent studies showed that SIK2 regulates the macrophage polarization to make a balance between inflammation and macrophage. Macrophage is critical to initiate immune regulation, however, whether SIK2 can be involved in immune regulation is not still well understood. Here, we revealed that the protein of SIK2 was highly expressed in thymus, spleen, lung, and brain. And SIK2 protein content increased in RAW264.7 and AHH1 cells with a time and dose-dependent after-ionizing radiation (IR). Inhibition of SIK2 could promote AHH1 cells apoptosis Moreover, we used the Cre-LoxP system to construc
