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.

Abstract: In accordance with the present invention, there is now provided a method for the diagnosis of amyloidosis, which comprises subjecting a protein sample such as serum, cerebrospinal fluid or brain tissues containing amyloid deposits obtained from a patient suspected of suffering from an amyloidosis related disease to measurement of the amount of ubiquitin in said sample, and comparing the resulting amount with the amount of ubiquitin in a normal healthy patient. In a second aspect of the present invention, there is provided a method for the diagnosis of Alzheimer's disease, which comprises subjecting a protein sample obtained from the brain extract or cerebrospinal fluid of a patient suspected of suffering from Alzheimer's disease to measurement of the amount of ubiquitin, and comparing the resulting amount with the amount of ubiquitin in a normal healthy patient.
