Research Field
Caspase-8 is a member of the death-inducing signaling complex in apoptosis. Deficiency of caspase-8 causes defects in the activation of T lymphocytes, B lymphocytes and natural killer cells, which leads to immunodeficiency, suggesting that caspase-8 has a postnatal role in immune activation of naive lymphocytes.
Nucleofection Experiments
Peripheral blood T lymphocytes (PBLs) were transfected with caspase-8 RNAi.
In addition, PBLs were co-transfected with a caspase-8 antisense construct and a plasmid coding for eGFP.
Expression of caspase-8-GFP fusion protein in PBLs from a caspase-8 deficient patient rescued the impaired induction of the activation marker CD25 after stimulation.
