Abstract: The present invention relates to a method for adjusting the affinity of a polypeptide to a target molecule by a combination of steps, including: (1) the identification of aspartyl residues which are prone to isomerization; (2) the substitution of alternative residues and screening the resulting mutants for affinity against the target molecule. In a preferred embodiment, the method of subtituting residues is affinity maturation with phage display (AMPD). In a further preferred embodiment the polypeptide is an antibody and the target molecule is an antigen. In a further preferred embodiment, the antibody is anti-IgE and the target molecule is IgE. In another embodiment, the invention relates to an anti-IgE antibody having improved affinity to IgE.

Abstract: Two classes of polypeptides derived from human IgE are described. One class binds selectively to the high affinity IgE receptor on mast cells and basophils, but not to the low affinity IgE receptor on B-cells, monocytes, eosinophils and platelets. The other class binds to the low affinity receptor, but not the high affinity receptor. The differential binding polypeptides of this invention are useful in diagnostic procedures for IgE receptors or in the therapy of IgE-mediated disorders such as allergies. They also are useful in preparing antibodies capable of binding regions of IgE that participate in receptor binding.

Abstract: The present invention describes IgE antagonists (including variant anti-IgE antibodies) and their use in diagnosis, therapy or prophylaxis of allergic and other IgE-mediated disorders, including asthma, food allergies, hypersensitivity and anaphylactic reactions.

Abstract: Humanized anti-CD11a antibodies and various uses therefor are disclosed. The humanized anti-CD11a antibody may bind specifically to human CD11a I-domain, have an IC50(nM) value of no more than about 1 nM for preventing adhesion of Jurkat cells to normal human epidermal keratinocytes expressing ICAM-1, and/or an IC50 (nM) value of no more than about 1 nM in the mixed lymphocyte response assay.

Abstract: IgE antagonists comprising one or more of the Fc.sub..epsilon. RI receptor-binding determinant sites of human IgE are described. The disclosed antagonists include IgE variants, peptide antagonists, peptidomimetics and other small molecules. The antagonists are useful in raising and screening anti-IgE antibodies, in the isolation and purification of Fc.sub..epsilon. RI receptor, and in the treatment of allergic disease.

Abstract: This invention concerns a method for the prevention and treatment of parasitic infection by administering an IgE antagonists. The invention further concerns pharmaceutical compositions and bispecific molecules useful in such method.

Abstract: A method is provided for administering to a mammal suffering from, or at risk for, a LFA-1-mediated disorder an initial dosing of a therapeutically effective amount of LFA-1 antagonist, followed by a subsequent intermittent dosing of a therapeutically effective amount of LFA-1 antagonist that is less than 100%, calculated on a daily basis, of the initial dosing of antagonist.

Abstract: A method is disclosed for stimulating a mammal's or avian's immune response, particularly immune-compromised mammals, by administration of IGF-I, alone or in combination with growth hormone. Preferably, the IGF-I is native-sequence, mature human IGF-I.

Abstract: The invention relates to the synergistic interaction of hepatocyte growth factor (HGF) and gamma-interferon (IFN-.gamma.) in the stimulation of hepatocyte growth. Accordingly, the invention concerns a method of enhancing the biological activity of HGF by administering a biologically effective amount of HGF and a synergistically effective amount of IFN-.gamma. to a patient in need.
