Abstract: A method of ameliorating the symptoms of sepsis comprising directly exposing epithelial cells of a mammal in need thereof to soluble CD14, or active variants thereof. A method of obtaining CD14 from a stock solution containing protein of a mammary secretion is described. A method of directly activating B cells using a soluble polypeptide having the amino acid sequence selected from the group consisting of leu-leu-leu-leu-leu-leu-pro-ser, leu-leu-leu-leu-leu-leu-pro-leu; and leu-leu-leu-leu-leu-leu-val-his, and which is specifically recognized by the monoclonal antibody 3C10 and which activates B cells is described. Bovine CD14 genomic DNA is described.

Abstract: A novel protein purified from bovine colostral whey and isolated nucleotide sequences encoding the protein is identified. The isolated bovine protein is termed Bovine Lactation Associated Immunotropic (Bo-LAIT) protein. The human homologue of Bo-LAIT protein, Hu-LAIT protein, is also described. A method of activating B cells, and particularly of activating B cells in a mammal, such as a human, in need of such activation by administering LAIT protein is described. LAIT protein can be incorporated into infant formula. LAIT protein can be administered to an infant, as by feeding to the infant such formula. LAIT protein can be incorporated as part of a vaccination. LAIT protein can be administered to a patient having a T cell immune deficiency, for example, a particular T cell dysfunction in which gp39 (CD40L) is under expressed on or totally absent from the cell surface of patient T cells.

Abstract: A novel protein purified from bovine colostral whey and isolated nucleotide sequences encoding the protein. The isolated bovine protein has homology with human CD14 and murine CD14 and so is referred to as bovine CD14. A method of activating B cells, and particularly of activating B cells in a mammal, such as a human, in need of such activation by administering CD14 is described. CD14 can be incorporated into infant formula. CD14 can be administered to an infant, as by feeding to the infant such formula. CD14 can be incorporated as part of a vaccination. CD14 can be administered to a patient having a T cell immune deficiency, for example, a particular T cell dysfunction in which gp39 is under expressed on or totally absent from the cell surface of patient T cells. Preparation of medicaments including CD14 for activating B cells in a mammal in need of such activation is described. Natural or recombinant CD14 can be used.
