WebAbstract. Multiple sclerosis (MS) is an inflammatory demyelinating disease affecting the central nervous system. Autoimmunity appears to play a key role in both susceptibility to MS and development of disease, and pathogenesis has been linked to defects in distinct regulatory cell subsets. B cells are known for their capacity to produce antibodies. WebParasitic helminths are among the most pervasive pathogens of the animal kingdom. To complete their life cycle, these intestinal worms migrate through host tissues causing significant damage in their wake. As a result, infection can lead to malnutrition, anemia and increased susceptibility to co-infection. Despite repeated deworming treatment, …
