WebTimeline of peripheral lymphocyte subpopulation counts, from July 2024 to September 2024. The CD4/CD8 ratio (normal range: 0.8–2) is shown underneath the graph for CD8 T cells. Before PAMS developed, the ratio was close to normal (0.79 in 07/20), and then remained consistently low due to highly increased CD8+ lymphocyte counts. WebNov 28, 2024 · Therefore, we further analyzed the subtypes of lymphocytes and found that the number of CD4 + and CD8 + T cells decreased as the severity of the disease increased. Meanwhile, the number of NK cells related to cellular immunity in the severe adenovirus pneumonia patients was also significantly reduced.
