title: [Dynamic Changes of the Quantitative Distribution,Apoptosis and Proliferation of T and B Cells in the Skin of KM Mutant Mice].
abstract: OBJECTIVE
  To observe the change of quantitative distribution,apoptosis and proliferation of T and B cells in the skin of KM mutant mice.
  
  
  METHODS
  We chose 1-,3-,6-,9-,22-day,3-,6-month-old KM mutant and wild-type mice to detect the changes of T and B lymphocytes using blood routine tests and immunohistochemical staining. Apoptosis was detected by TUNEL staining and proliferation by proliferating cell nuclear antigen (PCNA) staining.
  
  
  RESULTS
  T cells on KM mutant mice skin were mainly seen in epidermis and dermis. They increased on the first day to 6(th) day after birth and decreased on the 9(th) and 22(nd) day,but after 3-month-old,their number began to increase;at the time of 6 months,the number of B cells also increased. The apoptosis of the skin hair follicle and sebaceous gland cells were more obvious in KM mutant mice than in wild-type mice,with the maximal apoptosis occurred at the age of 22-day-old in both groups. The proliferation of epidermal basal cells in KM mutant mice between 1 to 9-day-old was not significantly different from that in the wild-type mice,but decreasing on the 22(nd) day and 3(rd) month and increasing in the 6(th) month. The proliferation in hair follicle and sebaceous glands decreased on 9(th) day,increased on 22(nd) day,and deceased on the 3(rd) month again.
  
  
  CONCLUSIONS
  The quantitative distribution,apoptosis,and proliferation of T and B lymphocytes abnormally change in the skin tissue of KM spontaneous mutant mice. They may lead to immune and hair growth disorders and promote the inflammatory responses.
