Isolation and Culture of Mouse Primary Microglia and Oligodendrocyte Precursor Cells.

Microglia and oligodendrocyte precursor cells (OPCs) are critical glia subsets in the central nervous system (CNS) and are actively engaged in a body of diseases, such as stroke, Alzheimer's disease, multiple sclerosis, etc. Microglia and OPC serve as compelling tools for the study of CNS diseases as well as the repair and damage of myelin sheath in vitro. In this protocol, we summarized a method which is capable of using the same batch of new-born mice to isolate and culture microglia and OPCs. It integrates the characteristics of practicality, convenience, and efficiency, providing a convenient, easy, and reliable technique for research.

T Cell Subsets and Immune Homeostasis.

T cells are a heterogeneous group of cells that can be classified into different subtypes according to different classification methods. The body's immune system has a highly complex and effective regulatory network that allows for the relative stability of immune system function. Maintaining proper T cell homeostasis is essential for promoting protective immunity and limiting autoimmunity and tumor formation. Among the T cell family members, more and more T cell subsets have gradually been characterized. In this chapter, we summarize the functions of some key T cell subsets and their impact on immune homeostasis.
