PI3K delta (PIK3CD)

Short target page →

The blood-cell version of the PI3K survival signal that keeps B cells alive. Idelalisib, duvelisib and copanlisib block it in chronic lymphocytic leukaemia and follicular lymphoma, at the price of immune-related colitis, liver inflammation and infections that have limited their use. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology
