The present invention relates to a method for treating an autoimmune disease, such ulcerative coliteis or crohns disease characterized by lymphocyte accumulation at epithelial sites. The method involves administering to a subject an effective amount of an antibody that selectively binds to an &agr; &bgr; integrin or an &agr; subunit thereof.

Method of treating ulcerative colitis or crohn's disease by administering an antibody to&agr;E&bgr;7 integrin

The present invention relates to antibodies that bind to a highly charged region of the integrin .alpha..sup.E subunit and its functional equivalents. The antibodies are useful in screening assays to identify agents which mimic the ligand-binding site on the integrin .alpha..sup.E.

Antibodies to integrin alpha subunit

The present invention relates to a novel integrin .alpha..sup.E subunit and its functional equivalents. The method for screening a molecular library to identify lead compounds which mimick the in vivo activity of an integrin .alpha..sup.E chain is disclosed. The invention further includes pharmaceutical compositions containing the isolated peptides, oligonucleotides encoding the peptides, vectors containing the oligonucleotides, and cell lines transfected with the vectors.

Integrin alpha subunit

Methods and compositions for preparing a mouse model of an inflammatory skin condition are disclosed. The methods involve administering donor lymphocytes to a recipient immune deficient mouse to induce the inflammatory skin response. The mouse models are useful for testing the efficacy of a therapeutic agent for treating the inflammatory skin condition. In particular, the mouse models are useful for screening therapeutic agents for treating human psoriasis.
