The response of living tissue to injury, featuring widening of blood vessels, with redness, heat, swelling and pain-the cardinal signs ‘rubor’, ‘calor’, ‘tumor’ and ‘dolor’ of the first century physician Celsus. Inflammation also involves loss of function and is the commonest of all...

The basic fuel of the body is a simple form of sugar called glucose. This comes to the liver as one of the products of digestion, and is converted into glycogen for storage. It is reconverted to glucose, when necessary, to keep up a steady level of sugar in the blood. This is ...
vessels, where their presence stimulates infiltration by lymphocytes, plasma cells, eosinophils, and thrombocytes (a condition known as lymphangitis). Because of the chronic nature of the illness, granulomas, fibrosis, and blocking of the lymphatic system may eventually occur. Over time, these ...
Formation of new lymphatic vessels is regulated by VEGF-C and VEGF-D, whereas VEGF-A facilitates the recruitment of monocytes, which activate lymphoangiogenesis (Murdoch et al., 2008). VEGF-A produced by myeloid cells also inhibits pericyte maturation and endothelial coverage of newly formed blood...
Activated endothelial cells promote leukocyte recruitment at inflammatory sites; new blood vessel formation, a process called angiogenesis, sustains chronic inflammation, and lymphatic vessels transport antigens and antigen-presenting cells to lymph nodes, where they stimulate naive T and B lymphocytes to ...
After arriving in the adipose tissue, monocytes can efflux into surrounding lymph nodes or back into the circulation (Auffray et al., 2007; Palframan et al., 2001). In obesity, there is increased adipose tissue expression of Semaphorin 3E and Netrin-1, which inhibit this emigration process, ...
3.2 Activation of toll-like receptors (TLR) A family of innate immune proteins called TLR is involved in the ocular surface inflammation of DED. TLR is one of the primary innate immune mechanisms that can be activated not only by pathogen associated molecular patterns (PAMPs) on pathogens, but...
Endothelial cells, which line the blood and lymph vessels, control the movement of proteins from the blood into the tissue. However, as discussed here, these often overlooked cells are also active participants in and regulators of the inflammatory proces
