CXCL13 and myasthenia gravis: To analyze B cells and TECs as possible targets of EBV in thymoma, we firstly evaluated the degree of B cell infiltration in our thymoma samples, showing a higher number of B cells in MG versus non-MG thymomas, likely related to an increased expression of the B cell-attracting chemokine CXCL13 (Figure 3D), in line with previous reports [47–49].
