Human monocytes/macrophages display a variety of cell-surface determinants to which monoclonal antibodies (MAbs) have been produced. These MAbs can be used to characterize phenotypic profiles of monocytes/macrophages to gain insight into their developmental and activation status. The basic and alternate protocols in this unit describe flow cytometry methods for measuring the expression of membrane determinants using directly conjugated or unconjugated MAbs, respectively. Because cells of this lineage display characteristic membrane marker patterns, combinations of MAbs are used in three-color analysis to facilitate immunophenotypic characterization. Detailed information and commercial sources of fluorochrome-labeled MAbs are provided, and suggested combinations of these MAbs for three-color flow cytometry analysis of cell suspensions are discussed.

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
Cells of the Innate Immune Response01:28

Cells of the Innate Immune Response

The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
