Inflammation process

In the vasculature, ANG H not only increases contraction of smooth muscle cells, but is also able to induce vascular injury. This can be prevented by blocking NFkB activation [3] suggesting a link between ANG II and inflammation processes involved in the pathogenesis of arteriosclerosis (see below). Thus, ACE inhibitors not only decrease vascular tone but probably also exert vasoprotective effects. 

Our group is focused upon applications dealing with inhibitions of bacterial (E. coli, Streptococcus suis) and viral (flu) infections, selectins involved in inflammation processes, acute rejection following xenotransplantation, homing of... 

COX-1 is found in healthy individuals and is important in maintaining a balanced physiological role in kidneys and stomach. COX-2, on the other hand, is induced in the case of inflammation where it mediates the inflammation process. Aspirin, ibuprofen, and naproxen inhibit both COX-1 and COX-2 indiscriminately. While this reduces the production of PGE2 through the inhibition of COX-2, it upsets the hemostasis function of COX-1, which has a protective function for the mucosal lining, and leads to bleeding and ulcer formation. 

This ligand has a lower affinity for adenosine A, and A2B receptors with pK values <6. A potent inhibitory effects on the generation of reactive oxygen species from human neutrophils and eosinophils and on the degranulation of human granulocytes subsequent to treatment with compound 30 have been described. This findings provide a useful tool for the understanding of the involvement of A2a and A3 ARs in inflammation processes. 

The most important activity of cyclosporin A consists clearly in the marked suppression of antibody formation and cell-mediated immune response [4, 5]. In addition, the metabolite exhibits antiphlogistic effects, restricted to chronic inflammation processes, as well as antifungal and antiparasitic activities. Whether these different biological activities are inter-related or represent separate mechanisms is still an open question. Considering immunosuppression, early observations revealed that cyclosporin A acts selectively on lymphocytes, mainly on T cells, affecting rather the inductive phase than the proliferative phase of lymphoid cell populations. Apparently, cyclosporin A inhibits primary T-helper cell activation and blocks the formation of... 

The effect of a surfactant on skin depends on the type of surfactant as described earlier. Wilhelm et al. demonstrated the irritation potential of anionic surfactants.21 They evaluated the effects of sodium salts of n-alkyl sulfates with variable carbon chain length on TEWL and found that a C12 analog gave a maximum response. They suggested that the mechanisms responsible for the hydration of SC are related to the irritation properties of the surfactants. Leveque et al. also suggested22 that the hyperhydration of SC is consecutive to the inflammation process. They demonstrated that the increase of TEWL was induced by SDS without removal of SC lipids. SDS might influence not only SC barrier function, but also the nucleated layer of epidermis and dermal system associated with inflammation.23 Recently, no correlation was found between the level of epidermal hyperplasia and TEWL increase on the SDS-irritated skin.23 Further work would be needed to determine the effects of surfactants on skin. 

Abgenix has begun clinical trials investigating a human monoclonal antibody (ABX-IL8) that binds interleukin-8 (IL-8), a protein that mediates inflammation process. Other studies have demonstrated that elevated levels of... 

Selectin-dependent adhesion inhibitors offer a new therapeutical approach to the prevention of transplant rejection. They should also enable treatment and prophylaxis of various other pathological inflammation processes and diseases (i.e. rheumatic arthritis, dermatitis and bacterial meningitis) initiated by a massive invasion of leucocytes [1,7]. 

Bradykinin is a vasoactive nonapeptide which is the most important mediator generated by the kinin system and it is involved in inflammation processes (Calixto et al, 2000). Kinins so far identified include bradykinin and kallidin. They cause local increases in the permeability of small blood vessels. Bradykinin is a potent stimulator of pain receptors in the skin and has a powerful influence on stimulating smooth muscle contraction, inducing hypotension, and increasing blood flow and permeability of capillaries Cyvetal, 2001). 

The product was also compared to Fuller s earth in a pig model. The potency of the RSDL/sponge was statistically better than Fuller s earth against skin injury induced by sulfur mustard, observed 3 days post-exposure. RSDL was more efficient than Fuller s earth in reducing the formation of perinuclear vacuoles and inflammation processes in the epidermis and dermis. The potencies of the RSDL/sponge and Fuller s earth were similar to severe inhibition of plasma cholinesterases induced by VX poisoning. Both systems completely prevented cholinesterase inhibition, which indirectly indicates a prevention of toxic absorption through the skin (Taysse et al, 2007).

An infection occurs when microorganisms colonize inside the body and use the body s resources to grow. This process interferes with normal body functions. The body s response may be the inflammation process (see chapter 12) however, colonization does not always cause signs and symptoms of disease and may not require treatment.
