Ep. 115: “Intercellular Communication” Featuring Dr. Harikesh Wong
Description
Guest:
Dr. Harikesh Wong is an Assistant Professor at the Ragon Institute and MIT, where his lab studies the design principles of the immune system. He talks about how Tregs constrain conventional T cell responses during infection, and advanced fluorescence microscopy techniques to study immune responses. (38:11 )
Featured Products and Resources:
- Stay up-to-date with the latest in immune regulation news.
- Learn how to isolate highly pure immune cells and efficiently process human samples with a free, on-demand course on human immune cell isolation.
