Priming cancer for immunotherapy

Augmenting the responses to checkpoint inhibitors, which remove the “breaks” from the immune response, is a very popular area of research. The general concept is to turn immunologically cold tumors hot. For example, triple negative breast cancer (TNBC) is considered an immunologically cold tumor – anti-PD(L)1 therapy has shown responses of just 5-10%. Continue reading

Surprising Efficacy of Darzalex is not Solely Due to Anti-CD38 Activity on Myeloma Cells

We have previously reviewed anti-CD38 monoclonal antibody Darzalex (daratumumab) in multiple myeloma. Daratumumab targets CD38-expressing myeloma cells through a variety of immune-mediated mechanisms (complement-dependent cytotoxicity, antibody-dependent cell-mediated cytotoxicity, and antibody-dependent cellular phagocytosis) and direct apoptosis with cross-linking of receptors.

Chop Protein Suppresses the Immune Response in Cancer

The Chop protein, not to be confused with the CHOP chemotherapy regimen for lymphoma (Cyclophosphamide, Hydro doxorubicin – Adriamycin, Oncovin – vincristine, and Prednisone), is a multifunctional transcription factor. This 29 kda protein that is produced following unfolded protein stress in the endoplasmic reticulum, which then triggers apoptosis. Continue reading
