Genetically induced decay-accelerating factor (DAF) overexpression prevents adriamycin (ADR)-induced focal segmental glomerulosclerosis (FSGS) in mice. Pharmacologic inhibition of DAF cleavage reduces complement activation in the glomeruli and albuminuria in murine ADR-induced FSGS. Inhibition of complement activation represents a valuable therapeutic strategy for FSGS and, potentially, other glomerular diseases.

Myopia is one of the major public health conditions with significant complications. This study investigates the role of transforming growth factor (TGF)-β2, complement activation, and inflammasome pathways in myopia progression using a Brown Norway rat model. Myopia was induced, and complement regulation was manipulated using gene therapy via adeno-associated virus (AAV) vectors delivering CD55 or CD55 siRNA.

Pancreatic ductal adenocarcinoma (PDAC) is highly malignant, with a five-year survival rate of only 12 %. Exact diagnosis and intervention are critical for improving patient prognosis. Core fucosylation (CF) of proteins plays a vital role in the progression of various cancers, including PDAC.

Aim: Hereditary spherocytosis (HS) refers to a heterogeneous disorder varying in genotypic and phenotypic features manifested by the production of spherocytes. The diseased cells can be eliminated from the circulatory system either by macrophages in the spleen in the extravascular pathway or the intravascular pathway via the complement cascade. This study aimed to investigate the status of red blood cell (RBC) surface molecules CD55 (decay accelerating factor), CD35 (complement receptor type 1-CR1), CD59 (MACIF), CD47 (marker of self) and CD71 (transferrin receptor) from individuals diagnosed with HS.

In the early stage, our research group injected lentivirus carrying blood type A antigen into tumors as a drug, and the tumor volume of mice was significantly reduced. We speculate that the complement system plays an important role in anti-tumor therapy, but the specific components are unknown. A mouse model containing blood type antibodies was established.

Marginal zone (MZ) B cells bridge innate and adaptive immunity by sensing bloodborne antigens and producing rapid antibody and cytokine responses. When unregulated, MZ B cells are associated with autoimmunity. CD55 is a membrane-bound complement regulator that interferes with complement activation and is another important component of innate and adaptive immunity.
