CXCR5 and Behcet disease: We performed <i>ex vivo</i> flow-cytometric profiling of blood γδT and B cells, established a cell culture system to investigate plasma cell generation <i>in vitro</i>, and quantified anti-HSP60 autoantibody levels in BD and HC participants' serum and cell culture supernatants.<h4>Results</h4>BD patients with active disease displayed a significant increase in the frequency of cells CXCR5<sup>+</sup>PD-1<sup>+</sup> Vδ2 T cells resembling a follicular helper-like functional state.
