Rare SH2B3 coding variants in lupus patients impair B cell tolerance and predispose to autoimmunity.

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease with a clear genetic component. While most SLE patients carry rare gene variants in lupus risk genes, little is known about their contribution to disease pathogenesis. Amongst them, SH2B3-a negative regulator of cytokine and growth factor receptor signaling-harbors rare coding variants in over 5% of SLE patients.

DOCK2 Deficiency Causes Defects in Antiviral T-Cell Responses and Impaired Control of Herpes Simplex Virus Infection.

The expanding number of rare immunodeficiency syndromes offers an opportunity to understand key genes that support immune defense against infectious diseases. However, analysis of these in patients is complicated by their treatments and comorbid infections, requiring the use of mouse models for detailed investigations. We developed a mouse model of DOCK2 immunodeficiency and herein demonstrate that these mice have delayed clearance of herpes simplex virus type 1 (HSV-1) infections.

Zeb2 drives the formation of CD11c atypical B cells to sustain germinal centers that control persistent infection.

CD11c atypical B cells (ABCs) are an alternative memory B cell lineage associated with immunization, infection, and autoimmunity. However, the factors that drive the transcriptional program of ABCs have not been identified, and the function of this population remains incompletely understood. Here, we identified candidate transcription factors associated with the ABC population based on a human tonsillar B cell single-cell dataset.

Benefits of psychosocial rehabilitation programming in a treatment mall.

Psychiatric patients need educational interventions that help them recover and increase their ability to live and work independently following discharge from the hospital. The psychosocial rehabilitation treatment mall model is designed to meet this educational need. Treatment malls are a new approach to psychosocial rehabilitaion for patients in state psychiatric hospitals.
