CohortThe CM group consisted of 126 patients (75 males and 51 females) and aged between 14-77 years (mean age = 45.92 ± 14.54 years). The 126 patients had previously been pathologically diagnosed with CM at the First Affiliated Hospital of Nanchang University between March 2010 and December 2016. Seventy five C57BL/6 mice were grouped into the normal control, CM model, CM + AmB, sham and CM + PD-1 antibodies (Ab) groups. CD4+ and CD8+ T cells as well as microglia/macrophages were analyzed by means of flow cytometry.

Disease Introduction MechanismCrytococcosis is an opportunistic fungal disease, instigated by Cryptococcus neoformans or Cryptococcus gattii infections. The infection typically initially attacks the lungs followed by spreading to other organs as well as the central nervous system (CNS) [Zhu et al., 2014]. The CNS is usually infected by an opportunistic infection when the CD4 T-lymphocytes density is lower than 200 cells per μL.
