Abstract: The invention relates to isolated and/or recombinant nucleic acids which encode a human chemotactic cytokine designated human eotaxin, and to isolated and/or recombinant human eotaxin proteins or polypeptides, including synthetic polypeptides. The invention further relates to recombinant nucleic acid constructs, comprising a nucleic acid which encodes a human eotaxin, a portion thereof, or a variant; to host cells comprising such constructs, useful for the production of recombinant human eotaxin; and to antibodies reactive with human eotaxin, useful in in vitro methods, diagnosis and/or therapy. Also provided are methods of use of the eotaxin proteins, e.g., in the recruitment of eosinophils to a particular site or in the treatment of allergic conditions. Human eotaxins can be used to identify inhibitors (e.g., antagonists) or promoters (agonists) of human eotaxin, which can be used to selectively modulate leukocyte function, in inflammatory and autoimmune diseases, or in infections.

Abstract: The present invention relates to humanized immunoglobulins having binding specificity for ?4?7 integrin, comprising an antigen binding region of nonhuman origin (e.g., rodent) and at least a portion of an immunoglobulin of human origin (e.g., a human framework region, a human constant region). In one embodiment, the humanized immunoglobulin can compete with murine Act-1 for binding to human ?4?7 integrin. In a preferred embodiment, the antigen binding region of the humanized immunoglobulin comprises each of the complementarity determining regions of the light and heavy chains of the murine Act-1 antibody.

Abstract: The present invention is based, at least in part, on the finding that tolerance can be induced by inhibition of CD4+ and CD8+ T cells. Accordingly, the methods of the invention are useful in treating a primate, e.g., a human, by inhibiting CD4+ and CD8+ T cells to induce tolerance to at least one antigen, e.g., self or foreign, such as for inducting tolerance in a primate against a transplanted antigen, e.g., an allogeneic or xenogeneic transplanted antigen.
