  • Antagonists of interleukin-15
    Patent number: 5795966
    Abstract: Antagonists of mammalian interleukin-15 ("IL-15") are disclosed and include muteins of IL-15 and modified IL-15 molecules that are each capable of binding to the IL-15R.alpha.-subunit and that are incapable of transducing a signal through either the .beta.- or .gamma.-subunits of the IL-15 receptor complex. Also included are monoclonal antibodies against IL-15 that prevent IL-15 from effecting signal transduction through either the .beta.- or .gamma.-subunits of the IL-15 receptor complex. Methods of treating various disease states are disclosed, including treating allograft rejection and graft-versus-host disease.

  • Haptic to optic attachment for a soft iol
    Patent number: 4938767
    Abstract: A method of making an intraocular lens including providing a fixation member having a proximal end portion with the proximal end portion including an elongated filament, converting a region of said filament at said proximal end portion from a first configuration into a second configuration which is adapted to provide a mechanical interlock and molding an optic about the proximal end portion of the fixation member to form a mechanical interlock between the second configuration and the optic and to attach the fixation member to the optic.
