In particular, some genes involved in immune/inflammatory responses and infection (e.g., IL19, MAPK15, and SERPINB10) and components of a complement system (e.g., C4B, VTN, BDKRB1, and C4BPA) have not been previously reported regarding their expression and functions in human omental adipose tissue. The gene discussed is BDKRB1; the disease is infection.
