Current Research Efforts:

Autoimmunity develops as the consequence of a loss of tolerance to self-antigens. Investigations carried out by Dr. Daniel Mueller are leading to a better understanding of the biological and biochemical nature of immune self-tolerance. Of particular interest are those factors that determine whether prolonged and continuous antigen stimulation of a T cell will lead to an increase in the clone size and the development of protective (or pathological) effector function, or alternatively lead to functional inactivation (anergy) and T regulatory cell (Treg) differentiation. To approach this problem, Mueller's research team is currently using an assortment of genomics and bioinformatics techniques (scRNA-Seq, ATAC-Seq) to characterize gene regulatory patterns in CD4 T cells that are associated with anergy induction and Foxp3+ Treg generation. Candidate gene regulators are being interrogated within neonatal mice--a time at which peripheral tolerance induction is essential for the avoidance of autoimmunity.

Loss of T cell tolerance also allows for the expansion and differentiation of autoreactive B cells, and the development of B-dependent autoimmune disease. Currently, these biological principles are being investigated in models of CD4 T cell-mediated immunopathology using both monoclonal TCR-transgenic T cells as well as self-antigen specific polyclonal responder cells. Additionally, translational experiments continue to detail the repertoire of human autoreactive B cells in normal subjects as well as in patients with Rheumatoid Arthritis. Currently, experiments are exploring the role of Ig gene somatic hypermutation in the generation of arthritogenic B cells by biochemically characterizing the antigen specificity of families of autoreactive B cell antigen receptors all derived from the same B cell progenitor.
