Outline of Final Research Achievements |
CD180 (RP105) molecule is expressed on B cells. RP105 is associated with B cell function, survival and death. RP105-lacking B cells produce autoantibodies, including anti-ds-DNA antibodies in SLE. Large population of plasmablasts lacking RP105 are found in patients with systemic autoimmune diseases and take part in pathophysiology. We have studied clinical significance of RP105-negative B cells including plasmablasts in various immune-based diseases. We also analyzed the 5 sub-populations of plasmablasts in the various diseases. RP105-negative plasmablasts play crucial roles in systemic autoimmune and immune-based inflammatory disorders. Also, distribution of sub-population and difference of expressed antigens in RP105-lacking plasmablasts may be associated with pathophysiology in individual disorders.
