Although there were calls from conference 'break-out' sessions for better stratification of MS patients in epidemiological studies, the consensus of studies pointing in the direction of an environmental cause, as well as the evidence from the oligoclonal immune responses, convinced the majority of delegates that MS is likely to be caused or triggered by an infectious agent. tuberculosis, even though a strong immune response involving both CD4 ϩ and CD8 ϩ T cells and production of IFN-␥, TNF-␣ and other cytokines is present.	./cache/cord-271176-wdc4p4bc.txt	./txt/cord-271176-wdc4p4bc.txt
