Monocyte Chemoattractant Protein 1 Required for Human Monocyte Chemotaxis Is 2 Calcium - Independent Phospholipase A

Calcium-independent phospholipase A(2) is required for human monocyte chemotaxis to monocyte chemoattractant protein 1.

Monocyte chemoattractant protein 1 (MCP-1) has an important influence on monocyte migration into sites of inflammation. Our understanding of the signal transduction pathways involved in the response of monocytes to MCP-1 is quite limited yet potentially significant for understanding and manipulating the inflammatory response. Prior studies have demonstrated a crucial regulatory role for cytosol...

A simple method for human peripheral blood monocyte isolation.

We describe a simple method using percoll gradient for isolation of highly enriched human monocytes. High numbers of fully functional cells are obtained from whole blood or buffy coat cells. The use of simple laboratory equipment and a relatively cheap reagent makes the described method a convenient approach to obtaining human monocytes.

Reticuloendothelial cell function in autoimmune hemolytic anemia (AIHA): studies on the mechanism of peripheral monocyte activation.

We examined the activity of peripheral blood monocytes in patients with autoimmune hemolytic anemia (AIHA) using an in vitro assay of monocyte-macrophage interaction with erythrocytes and an antibody-dependent cell-mediated cytotoxicity (ADCC) assay. The monocytes of AIHA patients in the hemolyzing period phagocytized autologous sensitized red cells and anti-D coated red cells more avidly than ...

Studies on Human Peripheral Blood Lymphocytes in Vitro

A study of the kinetics of RNA and DNA synthesis in PWM-stimulated lymphocytes revealed that RNA synthesis preceded the onset of DNA synthesis by approximately 24 hr and that DNA synthesis and transformation was maximal between 66 to 78 hr. Histochemical and radioautographic studies on PWM stimulated cultures indicated that at 72 hr 50 to 60% of the cell population had been transformed by PWM, ...
