Immunzellpopulation
Immunzellpopulation refers to a group of immune cells that share common characteristics, such as lineage, function, or location. These populations are crucial for the adaptive and innate immune responses that protect the body from pathogens and disease. Immune cells originate from hematopoietic stem cells in the bone marrow and differentiate into various lineages. Key immunocell populations include lymphocytes, such as T cells and B cells, which are central to adaptive immunity, mediating antigen-specific responses. Another major population is myeloid cells, encompassing neutrophils, macrophages, dendritic cells, and natural killer cells, which are involved in both innate immunity and bridging to adaptive immunity. The composition and activation status of these populations can vary significantly depending on the physiological state of the individual and the presence of infection or inflammation. Studying immunocell populations allows researchers to understand immune system function, identify biomarkers for disease, and develop targeted immunotherapies. Flow cytometry and single-cell sequencing are common techniques used to identify, quantify, and characterize different immunocell populations within complex biological samples.
