Jason,
We will add this to the Cell Ontology.
Please add cell type requests to the CL tracker:
https://sourceforge.net/tracker/?group\_id=76834&atid=925065
Thanks,
Alex

Thanks. Once added in the CL we will need in the MP terms: abnormal T-follicular helper cell differentiation abnormal T-follicular helper cell morphology abnormal T-follicular helper cell number increased T-follicular helper cell number decreased T-follicular helper cell number abnormal T-follicular helper cell physiology

Turns out we have "T follicular helper cell" in the hemo_CL file, but the term is not yet added to the main cell.obo file. I have asked Terry if the name should rather be "follicular helper T cell"?
I will keep you updated.

This is now a well established subset of CD4+ T cells, along side Th1, Th2. Generally ICOS+ CXCR5+, produce IL21. Recent papers I annotated that mentioned them J:157915, J:155586.
