Neonatal PMN (polymorphonuclear neutrophils) exhibit altered inflammatory responsiveness and greater longevity compared with adult PMN; however, the involved mechanisms are incompletely defined.

Protein-tyrosine phosphatase SHP-1 is a negative regulator of immune cell function and is broadly expressed in the hematopoietic compartment. Due to its role in immune cell signaling, SHP-1 may be ...

According to the results of research led by the Complutense University of Madrid (UCM), one the various strategies deployed by the Leishmania parasite to avoid triggering the human immune system is to ...

- Preclinical data identify SHP-1 as a downstream effector of GDF-15-mediated inhibition of T cell adhesion, further elucidating mechanistic details of GDF-15’s role in immunotherapy resistance. - ...

(A) Presence of PD-1, its ligands PD-L1 and PD-L2, and the phosphatases SHP-1, SHP-2, and SHP-2-like (SHP-2L) in representative jawed vertebrates, including sharks, ray-finned fish, amphibians, and ...
