This entire series is captivating and very informative, and I'm thankful its available to watch. I was just a bit frustrated however with the lecture on The New Biologic Agents: Transforming the Treatment of Autoimmune Diseasees, probably because the title lead me to expect a discussion...on the treatment of autoimmune diseases. I would love to hear more from Dr Gross on this subject, however in this lecture, he spent the first 20 minutes discussing what he wasn't going to talk about in the lecture (osteoarthritis and its causes and symptoms). Then for the remainder of the time, he focused mainly on the treatment of rheumatoid arthritis. I would love to hear a lecture that fit the title.
