Research Abstract |
Follicular helper T (Tfh) cells play a cardinal role in the production of high-affinity antibodies and their plasticity enables to become other effector helper T cells; however, regulatory mechanism of human Tfh cells is not fully elucidated. In this study we aimed to understand biomedical features of human Tfh cells. Results demonstrated that hypertrophic tonsils of the patients with obstructive sleep apnea syndrome preferentially possessed Tfh cells within enlarged lymphoid follicles. When examined blood Tfh cells of patients with immune-related disorders including allergic rhinitis or asthma, Tfh2 cells were predominantly observed. Thus far unusual manner of Tfh cell differentiation (named Tfh-shift or Tfh2-shift in this study) would be attributable for underlying conditions of such disorders. Further studies should be required, although ALOX5-related lipid mediators and/or POU2AF1 might be involved in the skewed differentiation of human Tfh cells.
