Materials and methods

Principles of method if other than guideline:
The in vitro production of IgG1, IgM, and IgA in supernatants from purified human CD19+
B-lymphocyte cultures, containing different concentrations of HEMA, was assayed with ELISA.
Proliferation was measured by [methyl-3H] thymidine incorporation.

Results and discussion

Any other information on results incl. tables

Of the different HEMA concentrations used, the lower concentrations of 15 and 37.5 µmol/L caused a significant increase in IgG1 production, but not in IgM or IgA production, in vitro. The lower HEMA concentrations did not significantly change B-cell proliferation. When B-cells were exposed to 75 μmol/L or 150 μmol/L HEMA, no significant changes in IgG1 were demonstrated. At the highest concentration of 750 μmol/L, HEMA significantly suppressed IgG1 and IgM production, as well as B-cell proliferation, in vitro.


 


 

Applicant's summary and conclusion

Conclusions:
In conclusion, HEMA can, at certain concentrations, selectively enhance human B-lymphocyte IgG1 production.
