Increased serum cyclophilin A concentrations could reflect trauma severity and unfavorable outcome after head trauma, substantializing cyclophilin A as a potential biomarker for prognostic prediction of TBI 1).
Cyclophilin A has been found to be involved in many inflammatory diseases via its receptor, cluster of differentiation 147 (CD147).
Cyclophilin A/CD147 interactions may participate in subarachnoid hemorrhage-induced early brain injury via increasing neuronal apoptosis pathway, at least partly through the ERK1/2-nuclear factor-κB pathway. Cyclophilin A/CD147 may be a suitable therapeutic target for subarachnoid hemorrhage 2).
Results provide evidence for the important contribution of CypA as a pertinent component acting through NF-κB-Sox9 in regulation of chondrogenesis signaling. These findings are important to better understand signal-induced chondrogenesis of chondrogenic progenitors in physiological and pathophysiological contexts 3).
