书接上回,继续对中性粒细胞亚群进行细分——
这回主要看看作者提出中性粒细胞以后干了些啥~
C4看起来不像中性粒细胞呀,其中RPL5
、RPS12
、RPL13
、RPL4
、RPL10
和RPL23A
都是核糖体相关蛋白而非中性粒细胞特异性marker,此外HLA-DPA1
、HLA-DPB1
和HLA-DRA
都是MHC-II型基因,似乎不表达于中性粒细胞?

2023年底才出来的新东西啊!Cui, A., Huang, T., Li, S. et al. Dictionary of immune responses to cytokines at single-cell resolution. Nature 625, 377–384 (2024). https://doi.org/10.1038/s41586-023-06816-9
做中性粒细胞基本抛不开中性粒细胞“成不成熟”的问题,文章因此也根据以往的文献对应的marker对这四个亚型进行了大致的界定:
