  • Publication number: 20140099321
    Abstract: Administration of an antibody that specifically binds IL-1? is useful for reducing the chance or severity of a major adverse clinical event occurring in a mammalian subject having received or expected to receive surgical treatment for a stenosed blood vessel, and for reducing the chance of restenosis occurring (or increasing the time until restenosis occurs) in a mammalian subject having received or expected to receive surgical treatment for a stenosed blood vessel.

  • Patent number: 8546331
    Abstract: The invention is based on the discovery that interleukin-1 alpha (IL-1alpha) is expressed on the proinflammatory CD14+CD16+ monocyte subset. Importantly, since IL-1alpha appears to be almost exclusively expressed on this monocyte subset and not other leukocytes, it represents an ideal marker for targeting the CD14+CD16+ monocyte subset. The effectiveness of an agent that depletes such pathogenic cells or modulates IL-1alpha function on such cells type can be monitored by assessing CD14+CD16+ monocyte levels or functionality.

  • Publication number: 20130018173
    Abstract: Antigen-specific immunoglobulin V-regions are identified from a library of nucleic acids amplified using polymerase chain reaction using leader sequence-specific forward primers. The use of leader sequence primers allows all V-region sequences to be amplified (including those with extensive 5? end mutations) without loss of the original 5? V gene segment sequence. A second V-region library is made using a larger than conventional set of 5? V-region primers. The sequence errors introduced into the amplification products by this method are corrected using sequence information obtained in the products amplified by the V-region primers to screen the library created using the leader sequence primers. Amino acid sequence information from fragments of donor immunoglobulins can be used to assist in the identification of nucleic acids encoding the heavy and light chains of donor antibodies as well as to design primers to amplify such nucleic acids.
