The present invention provides novel isolated BFLP1698 polynucleotides and polypeptides encoded by the BFLP1698 polynucleotides. Also provided are the antibodies that immunospecifically bind to a BFLP1698 polypeptide or any derivative (including fusion derivative), variant, mutant or fragment of the BFLP1698 polypeptide, polynucleotide or antibody. The invention additionally provides methods in which the BFLP1698 polypeptide, polynucleotide and antibody are utilized in the detection and treatment of a broad range of pathological states, as well as to other uses.
