AChR-MG  //

Alexa-AChR conjugate binding to BCR















 



Significantly increased numbers of AChR binding B cells, CD21+ and IgG+ cells have been observed in MG patients compared to healthy controls *.

Possible use of fluorophore-AChR or MuSK conjugate kit1

in flowcytometry:

 

  1. Test the frequency of AChR- or MuSK- binding B cells in peripheral blood2. That is measuring number of B cells potentially binding to fluorochrome-AChR or MuSK on the B cell receptor (BCR-surface immunoglobulin) in patients with MG and in animals with experimental autoimmune MG (EAMG).
     

  2. Test the frequency of AChR- or MuSK- binding B cells with other cell markers in the peripheral blood and thymus of patients with MG and animals with EAMG3.
     

  3. Test the frequency of AChR- or MuSK- binding B cells in seronegative MG.
     

  4. Test the frequency of AChR- or MuSK- binding B cells with other cell markers in patients with MG before and following immunosuppressive therapy including B cell depletion therapy with rituximab.
     

  5. Purify AChR- or MuSK- binding B cells with specific cell markers to perform detailed functional studies and genetic analysis in MG and EAMG. 
     

  6. Track AChR- or MuSK binding cells in EAMG in vivo.
