Human antibodies, preferably recombinant human antibodies that specifically bind to human Fas Ligand (hFasL) are disclosed. These antibodies have high affinity for hFasL, a slow off rate for hFasL dissociation and neutralize a Fas Ligand activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antigen-binding portions, of the invention are useful for neutralizing Fas Ligand activity, e.g., in a human subject suffering from a disorder in which hFas Ligand activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant anti-hFasL human antibodies, and the methods for synthesizing the recombinant human antibodies are also encompassed by the invention.
