Immunoglobulin A (IgA) nephropathy (IgAN) is the most common type of primary glomerulonephritis, often progressing to renal failure. IgAN is triggered by IgA deposition in the glomerular mesangium by an undefined mechanism. Here, we show that grouped ddY (gddY) mice, a spontaneous IgAN model, produce serum IgA against mesangial antigens, including βII-spectrin.

Patients with neuropsychiatric disorders often exhibit an altered metabolic status. However, the underlying factors that induce behavioral and metabolic dysfunctions remain poorly understood. Therefore, we investigated whether behavioral and metabolic alterations could be induced in immunodeficient conditions.

Accumulating evidence has suggested a correlation of tumor infiltrating B cells (TiBcs) and a good prognosis of cancer diseases. In some cases, TiBcs appear to have experienced antigen stimulation since they have undergone class-switching and somatic hypermutation and formed tertiary lymphoid structures around tumors together with T cells. Assuming TiBcs include those that recognize some tumor antigens, we sought to investigate their possible usefulness for cell-mediated immunotherapies.

The dialog between microbes and immune cells is critical for the establishment and maintenance of immune homeostasis. Bacterial-derived metabolites or structural components initiate immune signaling pathways and transcriptional factors, inducing a broad range of specificities and functional repertoires of the immune cells. Conversely, the immune system regulates the composition and function of bacterial communities.
