Abstract: Antibodies are disclosed which bind specifically to P-selectin and which block the binding of PSGL-1 to P-selectin. These anti-P-selectin antibodies may also cause dissociation of preformed P-selectin/PSGL-1 complexes. The disclosure identifies a heretofore unrecognized, near N-terminal, antibody binding domain (a conformational epitope) of P-selectin to which the function-blocking antibodies (which may be chimeric, human or humanized antibodies for example) bind. Antibodies are disclosed which bind to the conformational epitope of P-selectin and which have a dual function in blocking binding of PSGL-1 to P-selectin, and in causing dissociation of preformed P-selectin/PSGL-1 complexes. Such single and dual function anti-P-selectin antibodies and binding fragments thereof may be used in the treatment of a variety of inflammatory and thrombotic disorders and conditions. Screening methods for identifying such antibodies are also disclosed.

Abstract: There are many reports of diseases caused by overeating, satiation, and an unbalanced diet, and various therapeutic methods and therapeutic drugs are proposed for said diseases. There have not been many proposals, for prevention of these diseases, of methods by which what is eaten is not readily absorbed in vivo. The present invention involves inoculating female birds with a digestive enzyme as an antigen, said digestive enzyme being present in vivo. As a result of inhibiting the activity of the digestive enzyme by using an antibody which has been produced in vivo in the birds, the present invention inhibits decomposition of proteins, lipids, and carbohydrates and reduces in vivo absorption. This type of antibody can be obtained from an egg laid by a female bird which has received the antigen, and furthermore the egg itself includes the antibody. Consequently, a food product that contains, as an ingredient thereof, eggs having this type of antibody is low in proteins, lipids, and carbohydrates.
