title: [A study of susceptibility genes mapping for aberrant B1 cell proliferation in New Zealand mice].
abstract: OBJECTIVE
  To map the susceptibility genes for aberrant B1 cell proliferation in New Zealand mice.
  
  
  METHODS
  New Zealand Black (NZB) x New Zealand White (NZW) F1 x NZW backcross mice model was set up and polymorphic microsatellite markers and quantitative trait locus (QTL) analysis was used.
  
  
  RESULTS
  Susceptibility genes of aberrant B1 cell proliferation was linked to the microsatellite markers on chromosome 1, 4, 19 in NZB and on chromosome 17 in NZW such as D1Mit115, D4Mit58, D19Mit73 and D17Mit61 nearby which there existed Fcgr2b, c-jun, Fas and tumor necrosis factor (TNF)alpha, H-2 genes according to the QTL analysis.
  
  
  CONCLUSIONS
  B1 cell proliferation in New Zealand mice was controlled by multiple genes and the candidate susceptibility genes were Fcgr2b, c-jun, Fas derived from NZB strain and TNF alpha, H-2 genes derived from NZW strain.
