In this episode, Kellen speaks with Dr. Mitchell Kronenberg. Mitch is the chief scientific officer of the La Jolla Institute for Immunology, an adjunct professor at UC San Diego, and the co-director of a collaborative effort between the La Jolla Institute and UC San Diego called the Program in Immunology. Mitch and Kellen talk about unconventional T cells, autoimmunity, barrier immunity, chimeric antigen receptor (CAR) T cells, and the future of immunology. They also discuss Mitch’s philosophies related to science, mentorship, and life.

Correction: When Kellen mentioned the published CAR T trial in human autoimmunity, he misspoke and said multiple sclerosis (MS) but the trial he was referring to was in patients with lupus. That said, published preclinical data suggests CAR T therapy may also work in MS patients.

In this episode, Kellen speaks with Dr. Amir Zarrinpar. Amir is a board-certified gastroenterologist and an assistant professor at UC San Diego in the department of medicine. He completed his undergrad at Harvard, M.D. and Ph.D. at UCSD, and postdoc at the Salk Institute in Satchin Panda’s lab. In this conversation, Amir and Kellen talk about diabetes and obesity, time-restricted feeding, and engineered native bacteria—highlighting the Zarrinpar lab’s recent paper published in the journal Cell. Kellen and Amir also dig into Amir’s philosophies related to science, mentorship, and life.

In this episode, Kellen speaks with Dr. David Gonzalez. David is an associate professor at UC San Diego in the pharmacology department of the school of medicine and the Skaggs school of pharmacy. He’s also the founder and director of the UCSD collaborative center for multiplexed proteomics. The Gonzalez lab researches host-microbe interactions and specializes in proteomics approaches. Kellen and David talk about David’s inspirational journey to becoming a principal investigator. They also discuss proteomics, mentorship, and two of the Gonzalez lab’s recent publications related to inflammatory bowel disease (linked below).

In this episode, Kellen interviews Dr. Victor Nizet, a distinguished professor of pediatrics and pharmaceutical sciences at UCSD and the vice chair of basic research in the department of pediatrics at UCSD. Kellen and Victor discuss one of the Nizet lab’s recent publications (led by Josh Sun, Pharm.D. Ph.D.) identifying novel treatment strategies for Staph aureus-induced sepsis. Kellen and Victor also talk about Victor’s career path and scientific philosophies.

Omental adipose tissue has been considered an important component of host defense since at least 1906 when it was deemed “the policeman of the abdomen”. The precise mechanisms underlying omental host defense, however, remain elusive. Here, Kellen discusses a recent publication investigating how omental host defense works. The report titled “Stromal cells covering omental fat-associated lymphoid clusters trigger formation of neutrophil aggregates to capture peritoneal contaminants” was written by Lucy Helen Jackson-Jones et al. and published in Immunity April 2020.

Getting physically injured is no fun—it can often take long periods of time to recover. What if we could accelerate the wound healing process? Here, Kellen dissects an original article, titled “The commensal skin microbiota triggers type I IFN-dependent innate repair responses in injured skin”, that reveals mechanisms underlying skin injury and identifies novel therapeutic approaches to speed up healing. The report was written by Jeremy Di Domizio et al. and was published in Nature Immunology in July of 2020.

Cutting-edge approaches to combat tumor development involve transplantation of anti-tumor T cells and natural killer cells. Natural killer (NK) cells belong to a greater family of innate lymphoid cells which includes the more recently described group 1, 2, and 3 innate lymphoid cells (ILCs). Unlike NK and T cells, the role of non-NK ILCs in tumor immunity remains unclear. In this episode, Kellen highlights a 2020 report in Nature describing the role of ILC2s in pancreatic cancer. The article was written by John Alec Moral and colleagues and is titled “ILC2s amplify PD-1 blockade by activating tissue-specific cancer immunity”.
