WebAICD was unaffected by adhesion molecules or neighboring cells undergoing AICD, confirming the predominance of a suicidal mechanism. However, SEB was able to induce fratricidal apoptosis of type 1, but not type 2 cells. Fratricide was also observed when unstimulated T cells were exposed to activated Tc1 effector cells. WebNov 13, 2024 · Activation- induced cell death (AICD) is a programmed cell death caused by the interaction of CD95 and CD95L. Through specific blocking of the CD95-CD95L pathway, the CD95L inhibitor APG101 (Asunercept, Apogenix AG, Heidelberg) could prevent activated T cells from AICD.

In contrast, preactivated T cells undergo activation-induced cell death (AICD) in response to the same signal. 1-3 Apoptosis by AICD is an important mechanism to down-regulate the number of reactive T cells and to terminate …

The susceptibility of activated human CD8 T cells to TNF-induced cell death triggered by anti-CD3/CD28 mAbs stimulation was confirmed in terms of a stronger proteolytic activation of caspase 3 (Figure 1 A).

Webvia a Fas-FasL interaction6-10 (AICD through TNFR1 has also been suggested). Mice with defects in Fas or FasL (lpr and gld mice) suffer from lymphoproliferative disease, i.e., they accumulate lymphocytes as they age. Despite the unusual phenotype of these accumulating cells—they express the B cell marker B220 and not the T cell markers
FasL is primarily regulated at the transcriptional level. (The other option is regulation of the signal emanating from the death receptor itself, controlling sensitivity to the induction of apoptosis.) NFAT activated by TCR stimulation activates FasL transcription, possibly indirectly by upregulating early growth response proteins. T cell activation-induced transcription of FasL is further regulated by c-Myc–MAX heterodimers, and can be blocked by c-Myc downregulation.
