Abstract	We have developed in the amphibian Xenopus laevis a unique non-mammalian model to study the ability of certain heat shock proteins (hsps) such as gp96 to facilitate cross-presentation of chaperoned antigens and elicit innate and adaptive T cell responses. Xenopus skin graft rejection provides an excellent platform to study the ability of gp96 to elicit classical MHC class Ia (class Ia) restricted T cell responses. Additionally, the Xenopus model system also provides an attractive alternative to mice for exploring the ability of gp96 to generate responses against tumors that have down-regulated their class Ia molecules thereby escaping immune surveillance. Recently, we have developed an adoptive cell transfer assay in Xenopus clones using peritoneal leukocytes as antigen presenting cells (APCs), and shown that gp96 can prime CD8 T cell responses in vivo against minor histocompatibility skin antigens as well as against the Xenopus thymic tumor 15/0 that does not express class Ia molecules. We describe here the methodology involved to perform these assays including the elicitation, pulsing and adoptive transfer of peritoneal leukocytes, as well as the skin graft and tumor transplantation assays. Additionally we are also describing the harvesting and separation of peripheral blood leukocytes used for flow cytometry and proliferation assays which allow for further characterization of the effector populations involved in skin rejection and anti-tumor responses.
