Monoclonal anti inhibition

Inhibition of inflammatory cytokines (Fig. 2) Humanized monoclonal anti-TNF antibodies (Infliximab (Remicade ), Adalimumab (Humira )) bind with high selectivity to human TNF-a and neutralize its activity. Thereby, infliximab decreases the effects of enhanced TNF levels during inflammatory disease such as production of proteases, chemokines, adhesion molecules, cyclooxygenase products (prostaglandins), and proinflammatory molecules such as interleukin-1 and -6. The antibodies may also recognize membrane-bound TNF-a on lymphocytes and other immune cells. These cells may subsequently become apoptotic or are eliminated via Fc-receptor-mediated phagocytosis. 

Omalizumab is a recombinant humanized monoclonal anti-IgE antibody that inhibits binding of IgE to receptors on mast cells and basophils, resulting in the inhibition of mediator release and attenuation of the early- and late-phase allergic response. It may be a treatment option for moderate to severe persistent asthmatics 12 years of age or older whose asthma is not controlled by inhaled corticosteroids and who have a positive skin test or in vitro reactivity to perennial allergens.37 Omalizumab significantly decreases inhaled corticosteroid use, number and length of exacerbations, and increases asthma-related quality of life.37... 

TNF-rt effects cellular function via activation of specific membrane-bound TNF receptors (TNFRi, TNFR2). Administered soluble TNF receptors, by combining with soluble TNF-, can inhibit the effects of the endogenous cytokine. Monoclonal anti-TNF antibodies can, in theory, cross-link TNF receptors on the cell surface and inhibit T cell and macrophage function. Three drugs interfering with TNF- have been approved for the treatment of rheumatoid arthritis.

CK-2 levels are measured in numerous ways. The present discussion will concentrate on the immunoassays that use monoclonal anti-CK-2 antibodies.Immunoassays developed in recent years have improved on the analytical and chnicai sensitivity and specificity of the earlier immuno inhibition and immunoprecipitation assays. These assays now (1) measure CK-2 directly and provide mass measurements, (2) are easily automated, and (3) are rapid (<30 minutes). This allows laboratories the ability to offer...

Panel A shows the increased level ofDNA meth)dation in individual cells with monoclonal anti 5mC antibodies. Panel B reports the AFM images from which it was possible to measure how the presence of new methyl groups on DNA induces a mote condensed chromatin structure (for details see ref. 61).

A critical step in radioprotection involves the IL-1 receptors. Monoclonal antibodies to the type 1 IL-1 receptor block IL-l-induced radioprotection (167). Although this receptor is not present on BM cells, it is present on fibroblasts, which suggests that the effects of IL-1 on stem cells maybe largely indirect and mediated by stromal cell activation (168). Anti-IL-1 receptor (type 1) also sensitizes normal mice to the effects of TBI, which suggests that endogenous IL-1 has an intrinsic radioprotective role. IL-6 induction by IL-1, but not CSF levels, is inhibited, which supports the concept that G-CSF and GM-CSF are insufficient by themselves at radioprotecting stem cells and indicates a contributory role for IL-6. Anti-IL-6 antibody blocks IL-1 and TNF-induced radioprotection and also decreases the intrinsic radioresistance of mice, as does anti-TNF- a (169).

The involvement of mast cells in host protection against nematode infection is well characterized in T. spiralis infection. W/Wv mice exhibited a significant delay in worm expulsion, and treatment with either anti-SCF or anti-SCF receptor monoclonal antibody dramatically inhibited mast cell responses and expulsion of T. spiralis for the duration of treatment (Donaldson et al., 1996). W/Wv mice also lack interstitial cells of cajal and intraepithelial y T cells (Maeda et al., 1992 Puddington et al., 1994), which may contribute to the impaired response in these animals (see below). However, supporting evidence of a role for mast cells in protection against T. spiralis comes from studies in which overexpression of IL-9 in mice (which is known to influence the mast cell responses see above) resulted in an extremely rapid mast cell-dependent expulsion of T. spiralis (Faulkner et al., 1997).
