B Cells, T Cells, RA and Immunity

The next Immunology North East Seminar is at 5pm on Thursday 5th March 2014.  The seminar will be held in the Research Beehive Rm 2.21, Newcastle University and refreshments will be available from 4.30pm.  

 

 

Dr. Tom Barr, Institute of Infection, Immunity and Inflammation, University of Glasgow will present

 

“T follicular helper cells: Heterogeneity in phenotype and function”?

 

 

 

If you would like to speak to Tom during his visit please contact Dr Andy Knight andrew.knight@ncl.ac.uk

Brief Interests: I study B cells, the under appreciated workhorse of the immune system. These cells produce the antibodies that protect us from infection following vaccination but can also cause autoimmune disorders, such as rheumatoid arthritis. While recent research has focused on antibody production by B cells, I believe that their role in autoimmune disorders is much more complex -- so the fundamental question governing my work is “how else can B cells influence immunity?"
