WebOct 1, 2024 · The role of TDLNs as main hubs in providing anti-tumor T cell immunity following ICB furthermore fits with recent insights into PD-1/PD-L1 biology showing that PD-1 inhibits CD28-B7-mediated T cell co-stimulation, a process that takes place in a B7-rich environment such as LNs, and is less likely in the immune-suppressive tumor … WebDec 2, 2024 · Recognizing we needed to do something different, we came up with another type of bispecific: CD28 costimulatory bispecifics. These work similarly to CD3 bispecifics in bridging T-cells to cancer cells, but are designed to enhance T-cell activation via CD28 costimulatory signaling (so called “Signal 2” for T cell activation).
