In neurodegenerative diseases caused by extended polyglutamine (polyQ) sequences in proteins, aggregation-prone polyQ proteins accumulate in intraneuronal inclusions. PolyQ proteins can be degraded by lysosomes or proteasomes. Proteasomes are unable to hydrolyze polyQ repeat sequences, and during breakdown of polyQ proteins, they release polyQ repeat fragments for degradation by other ...

Accumulating evidence suggests that defects in the function of CD4(+)CD25(+) regulatory T cells (Tregs) are important in immune-mediated diseases such as rheumatoid arthritis. Here, we investigated the effects of various disease-modifying anti-rheumatic drugs (DMARDs) on Treg function. Tregs and CD4(+)CD25(-) effector T cells (Teffs) were isolated from peripheral blood mononuclear ...
