Gas6TAM Receptors in Systemic Lupus Erythematosus

Abstract EN

Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease associated with impaired immune system regulation.

The exact mechanisms of SLE development remain to be elucidated.

TAM receptor tyrosine kinases (RTKs) are important for apoptotic cell clearance, immune homeostasis, and resolution of immune responses.

TAM deficiency leads to lupus-like autoimmune diseases.

Activation of TAM receptors leads to proteolytic cleavage of the receptors, generating soluble forms of TAM.

Circulating TAM receptors have an immunoregulatory function and may also serve as biomarkers for disease prognosis.

Here, we review the biological function and signaling of TAM RTKs in the development and pathogenesis of lupus and lupus nephritis.

Targeting Gas6/TAM pathways may be of therapeutic benefit.

A discussion of potential TAM activation and inhibition in the treatment of lupus and lupus nephritis is included.
