Abstract: Provided is an immunosuppressive peptide of 40 kDa molecular weight, isolated from the submandibular glands (SMG*) of rats, having the capacity to suppress immune reactions upon parenteral administration to rats and mice. The peptide was identified as glandular kallikrein (K1) by partial sequencing and by enzymatic activity. Also provided are methods and compositions for Using K1 peptides in the treatment of autoimmune diseases.

Abstract: This invention relates to ?-hydroxyketones and ?-alkoxyketones of formula (I), to their use as estrogen receptor modulators, and to methods for their preparation.

Abstract: An immunosuppressive peptide of 40 kDa molecular weight, isolated from the submandibular glands (SMG*) of rats, had the capacity to suppress immune reactions upon parenteral administration to rats and mice. The peptide was identified as glandular kallikrein (K1) by partial sequencing and by enzymatic activity. Further experiments revealed that the excision of SMG (SMGx) from Lewis rats prevents the oral induction of immunological tolerance against native bovine type II collagen (BCII). Thus SMGx rats, when they were given oral BCII and were subsequently immunized with the same antigen, developed collagen induced arthritis (CA), while normal rats given an identical treatment were protected from the disease. When SMGx rats were orally given porcine K1 in conjunction with BCII, the capacity of such animals to develop oral tolerance was fully restored. These results indicate that normal SMG function is required for induction of oral tolerance and that K1 is involved in mediating this function.

Abstract: The invention relates to a method of sensitizing cancer cells for a killer cell mediated lysis which involves administering to a patient an effective amount of antiestrogen and killer cells either jointly or sequentially, wherein the killer cells are selected from the group of NK cells, LAK cells and CTL cells and the antiestrogen is selected from the group of triphenylethylene class antiestrogens, such as tamoxifen or toremifene or their pharmaceutically acceptable salt.
