Differential Diagnosis of Autoimmune Encephalitis from Infectious Lymphocytic Encephalitis by Analysing the Lymphocyte Subsets of Cerebrospinal Fluid

Figure 1

CD3, CD4, CD8, and CD20 in the CSF of patients with NMDAR-AE, HSVE, and TBM. The proportion of CSF CD20 cells was significantly higher in NMDAR-AE than that in other groups, while the proportion of CD3 cells was not obviously different among the three groups. Typical CD3 cells were marked in blue arrows in (a–c) for NMDAR-AE, HSVE, and TBM, respectively. Typical CD4 cells were marked in red arrows in (d–f) for NMDAR-AE, HSVE, and TBM, respectively. Typical CD8 cells were marked in green arrows in (g–i) for NMDAR-AE, HSVE, and TBM, respectively. Typical CD20 cells were marked in black arrows in (j–l) for NMDAR-AE, HSVE, and TBM, respectively.
