Abstract

To explore the inhibition pathway of the EBV-immortalized cells (CD23(+)) in children with infectious mononucleosis (IM) caused by Epstein-Barr virus. The expressions of CD23, CD19, CD95, Bcl-2 and the co-expressions of CD23CD95, CD19CD23 on peripheral blood mononuclear cell (PBMC) were analyzed by flow cytometry (FCM) during acute phase, early convalescent phase and convalescent phase of 34 EBV-IM children and compared with that of 24 healthy donors. (1) The levels of CD23(+) and CD23(+)CD19(+) cells decreased and CD95(+), CD95(+)CD23(+), Bcl-2(+) cells increased markedly in IM patients in acute phase [CD95(+) cells (19.43 +/- 8.46)%; CD95(+)CD23(+) cells (1.81 +/- 1.71)%; Bcl-2(+) cells (23.41 +/- 26.47)%] and early convalescent phase [CD95(+) cells (12.94 +/- 5.05)%; CD95(+)CD23(+) (1.05 +/- 1.20)%; Bcl-2(+) cells (10.54 +/- 9.68)%], as compared with those of healthy controls [CD95(+) cells (10.39 +/- 2.90)%; CD95(+)CD23(+) cells (0.50 +/- 0.46)%; Bcl-2(+) cells (7.25 +/- 2.88)%]. The earlier the course of IM, the more abnormal the expressive levels. All the abnormal results returned to normal in convalescent phase. (2) Positive relationships were observed between the expressions of CD95(+)CD23(+) cells and that of CD23(+) c...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
