T细胞CD4+记忆细胞是一类具有记忆功能的T细胞。当身体面对具有威胁性的抗原时,这些细胞会感应、分化并进一步成为不同类型的细胞来应对威胁。然而,在此过程中,一些细胞会留下并转变为记忆细胞,以备将来再次感应到相同抗原时能够更快地做出反应。 2. T细胞CD4+记忆细胞的功能 T细胞CD4+记忆细胞在人类免疫系统中发挥着多...

Unlike memory CD8 T cells and plasma cells, which reside in bone marrow niches, it had been presumed that memory CD4 T cells constantly circulate in the body for surveillance. Now, Tokoyoda and colleagues show that memory CD4 T cells do in fact reside and rest in the bone marrow, where ...

CD4+ T-Cell Memory CD4+ T cells differentiate and expand during an immune response to a particular invasion. Once infection is cleared, memory Th cells are generated over time following the death of the majority of effector cells. These memory cells can quickly respond to a secondary infection...
