Welcome


Cytotoxic cells, including natural killer (NK) cells and cytotoxic T cells, recognize and kill infected and transformed cells. Our laboratory investigates mechanisms of recognition of cancer cells and infected cells by natural killer cells and T cells. Furthermore we investigate mechanisms by which tumors and infectious agents naturally activate or inhibit productive responses by cytotoxic cells, or desensitize the cells by inducing anergy. Our aim is to harness these findings to improve existing immunotherapies for cancer and design new ones. We have employed our understanding of NK recognition, activation and inhibition to establish therapy combinations that super-activate NK cells, while at the same time preventing desensitization and inhibition of the cells.  These combinations show promise as new therapies for cancers that are refractory to existing immunotherapies.

Immunotherapy of cancer by NK cells induced by STING agonists and superkine. 

News and Announcements:

Welcome to new postdoctoral fellow, Hannah Ghasemi! October 2023

See our comprehensive review of NK cells in cancer and immunotherapy, in Nature Reviews Immunology: "Roles of natural killer cells in immunity to cancer, and applications to immunotherapy”. February 2023

In a collaborative study with Chris Garcia's lab, we (Yeara Jo) contribute to showing that induced proximity of NK inhibitory recepts with CD45 phosphate is more effective than simple blockade in unleashing NK killing. Inactivating CD94/NKG2A and two Ly49 receptors simultaneously was much more effective than seperately inactivating them. September 2022.

Djem Kissiov’s paper is now out in eLife! Important new findings in NK receptor gene expression mechanisms and random monoallelic gene expression generally. Also has remarkable finding that numerous lineage defining genes (i.e the genes for CD45, Thy-1, CD8a) show a low degree of random monoallelic expression, suggesting that RME may be a universal property of gene expression. May 2022

Natalie Wolf’s paper is now out in PNAS! It shows remarkable synergistic effects of combining STING agonists and an IL-2 superkine in immunotherapy of cancer in numerous mouse models of cancer, including primary sarcomas (with the critical collaboration of Cristina Blaj). This was a “winning combination” for MHC-deficient tumors (where NK cells and CD4 T cells mediated rejection) and MHC I+ tumors (where CD8 T cells and--in the primary tumor model—CD8 cells, CD4 cells and NK cells mediate rejection). This may be an approach to resurrect STING agonist immunotherapy and IL-2 superkine therapy alike. May 2022

Sadly, Natalie Wolf is heading out for the next chapter in her career. It has been a ton of fun to have her in the lab these last years and she accomplished a great deal! Best of luck Natalie!  May 2022

Congratulations to our former colleague, Jim Allison, for his Nobel Prize in Medicine and Physiology— given for his work on cancer immunotherapy at UC Berkeley in the 1990's! We collaborated then to show that CD28 is the constimulatory molecule for T cells. Proof that basic research in animal models transforms human health! See the press release here

Congrats to Assaf Marcus for having his paper accepted in Immunity
