Definitions
- the invention relates to use anti-IgE antagonists, including monoclonal
- Immunoglobulin E is one class of immunoglobulin (or "antibody")
- IgE is present in human serum in lower concentrations than the other
- immunoglobulins IgG, IgM, IgA, and IgD.
- IgE is thought to have a role in protection
- IgE is well known as the mediator of
- IgE In IgE-mediated allergic reactions, IgE, after it is secreted by B cells, binds
- IgE molecules and hence the underlying receptors, and triggers the release of
- pharmacologic mediators such as histamine, serotonin, leukotrienes and the slow-
- dermatitis is characterized by pruritis (itching), redness, and painful skin lesions.
- the skin can become lichenified.
- atopic dermatitis may have a link to IgE, but that IgE alone is not the causative
- a particular class of anti-IgE antibodies has been developed to treat allergic
- anti-IgE antibodies also bind to IgE which is attached to the membrane of IgE-
- B cells the "membrane form of IgE". By doing so, they may further aid
- ADCC ADCC
- complement mediated cytolysis the IgE-producing B cells
- Such antagonists would include small

- Another humanized antibody suitable for treatment of atopic dermatitis is Another humanized antibody suitable for treatment of atopic dermatitis.
- E25 (rhuMAb-E25), produced by Genentech, Inc. This antibody is described in
- mice were immunized several times with polyclonal human IgE from sera
- hybridomas resulting from the fusion were then screened by enzyme-
- TES-C21 was further screened, by ELISA, to be specific for human IgE, and
- IgG IgM, IgA, IgD, human serum albumin, transferrin or insulin.
- TES-C21 bound equally well to various human IgE molecules. TES-C21 bound to
- murine cell line of SE44 or to a murine cell line secreting chimeric human IgG.
- TES-C21 also does not bind to IgE on high affinity Fc ⁇ RI receptors or on low affinity
