Human peripheral-blood monocytes, when cultured in the absence of serum, are prevented to differentiate to macrophages (Mφ). Instead, they develop into accessory cells which by various properties resemble dendritic cells. Signals that control development either into Mφ or monocyte-derived accessory ...
The recruited monocytes at active inflammation foci differentiate into macrophages releasing MMP-9 through positive feedback and perturbation of the TNF-α and/or NF-κB signal pathway. Stereotaxic elastase injection into the cerebrospinal fluid space also causes MMP-9 activation and ECM digestion ...
What are released by activated T cells and macrophages to mobilize immune cells and attract other leukocytes into the area? a. cytokines b. perforins c. interleukin 1 proteins d. interleukin 2 proteins Which of the following cells are antigen-presenting cells? (a) NK...
We propose that DCs should be classified as a separate lineage of mononuclear phagocytes on the basis of the fact that they arise from adult haematopoietic stem cell (HSC)-derived precursors that are distinct from the precursors of monocytes and macrophages (Fig. 1). Dendritic cells : The prof...
Indeed, it was recently found that monocytes rapidly phagocytose infused MSCs45. Our finding that some IA-injected MSCs were entrapped in the lung of one recipient rat, 1 day after injection, is in line with these earlier reports. However, we found no evidence of permanent engraftment in ...
However, many of these are unable to differentiate between cells that have truly been phagocytosed and those still present on the surface of the macrophages hindering exact assessment of efferocytotic capacity. We herein describe AnxA5-pHrodo and its negative control M1234-pHrodo as new ...
What are the functions and characteristics of eosinophils, lymphocytes, macrophages, monocytes, natural killer cells, and neutrophils? What are large cells that play an important defensive role by engulfing pathogens and cell debris? Which of the following cell type(s) produ...

joint from the bloodstream in response to chemotactic signals such as MCP-1, directing them to foci of inflammation. Once infiltrating synovial tissue, monocytes differentiate into macrophages and dendritic cells, which play a key role in maintaining the chronic inflammation characteristic of RA [32,...
