P38 Antibody: RPE

Rabbit Anti-Human p38 Polyclonal

Product Specifications

Background

P38 is a member of the mitogen-activated protein kinase (MAPK) family, specifically involved in cellular responses to stress and inflammation. In the nervous system, p38 plays a pivotal role in regulating apoptosis, neuroinflammation, and synaptic plasticity—processes that are frequently dysregulated in neurodegenerative diseases. Upon activation by environmental and cellular stressors such as oxidative damage, cytokines, and UV radiation, p38 translocates to the nucleus where it modulates transcription factors and pro-apoptotic proteins. This leads to the release of cytochrome c, activation of caspase-3, and cleavage of PARP, promoting programmed cell death. In Alzheimer’s, Parkinson’s, and ALS, aberrant p38 signaling contributes to neuronal loss, glial activation, and neurodegenerative phenotypes. As a result, p38 has emerged as a therapeutic target for modulating neuroinflammation and preventing neuronal degeneration.
