Breaking the balance between effector T cells, including Th17 (T helper cell 17) cells, and regulatory T cells (Tregs) is a key link in the pathogenesis of rheumatic immune diseases, which lead to a new concept of regulating immune balance in the treatment of rheumatic immune diseases. Interleukin (IL)-2 can effectively regulate the differentiation, development and functional activity of regulatory T cells, thus restoring the immune balance between regulatory T cells and effector T cells. Therefore, low-dose IL-2 has been used in the treatment of rheumatic immune diseases, and it has become a promising new choice to achieve therapeutic purpose by regulating the immune balance of T cell. Here, we discuss the role of T cells immune imbalance in the pathogenesis of rheumatic immune diseases and the mechanism of IL-2 in the treatment of rheumatic immune diseases by regulating T cells immune balance and summarize the relevant clinical trials.

Isolation of Functional Cardiac Immune Cells

This method for isolating functional immune cells from the heart provides an alternative to the conventional methods of collagenase digestion, which causes unwanted immune cell activation, resulting in a decreased responsiveness of these cells. Our method of isolation yields functional cardiac immune cells by avoiding problems associated with enzymatic...

Studying Organelle Dynamics in B Cells During Immune Synapse Formation

Herein we describe two approaches to characterize cell polarization events in B lymphocytes during the formation of an IS. The first, involves quantification of organelle recruitment and cytoskeleton rearrangements at the synaptic membrane. The second is a biochemical approach, to characterize changes in composition of the centrosome, which undergoes polarization to the immune synapse.
