Immunotherapy aims to boost a patient’s own immune system to fight disease. Activation of T cells via direct stimulation of the T cell receptor or by modulating immune checkpoint pathways are two strategies being employed individually and in combination. Immune checkpoint targets include co-inhibitory (e.g. PD-1, CTLA-4, TIGIT, LAG-3) and co-stimulatory (e.g. GITR, 4-1BB, OX40, CD40) receptors.
Primary Human Hepatocyte (PHH) culture provides the closest in vitro model to human liver that can produce a metabolic profile of a given drug very similar to that found in vivo. Recently we have developed an easy-to-assemble user-friendly in vitro Primary Human Hepatocyte (PHH) 3D-spheroid modelREAD MORE
