Human leukocyte antigen (HLA) B27 (subtypes B*2701-2759) [1] is a class I surface molecule encoded by the B locus in the major histocompatibility complex (MHC) on chromosome 6 and presents antigenic peptides (derived from self and non-self antigens) to T cells.

2010年1月18日 · HLA-B27 gives an intriguing insight into the connection between heredity and disease. As well as its close links with SpA, various other associations have been reported between B27 and diseases of different organs and systems. Evidence is also accumulating that it mitigates the virulence of HIV and other viral infections.

2018年11月13日 · Although most HLAs protect your body from harm, HLA-B27 is a specific type of protein that contributes to immune system dysfunction. The presence of HLA-B27 on your white blood cells can cause your...

Haemophilus influenzae (formerly called Pfeiffer's bacillus or Bacillus influenzae) is a Gram-negative, non-motile, coccobacillary, facultatively anaerobic, capnophilic pathogenic bacterium of the family Pasteurellaceae. The bacteria are mesophilic and grow best at temperatures between 35 and 37 °C. [1]

Haemophilus influenzae includes six encapsulated types, a through f, as well as nonencapsulated or untypeable strains, and these are found as both respiratory tract commensals and respiratory and invasive pathogens.
