A transistor comprises: an insulating layer; a semiconductor layer provided on a major surface of the insulating layer; a gate insulating layer provided on the base region; and a gate electrode provided on the gate insulating layer. The semiconductor layer has a source portion having a plurality of source regions of a first conductivity type and a plurality of base contact regions of a second conductivity type, the source regions being alternated with the base contact regions, a drain portion of the first conductivity type, and a base region of the second conductivity type provided between the source portion and the drain portion, the base region being in contact with the source regions and the base contact regions. A junction between the source regions and the base region is closer to the drain portion side than a junction between the base contact regions and the base region.

A novel process for preparing tumor-specific T cells is disclosed. According to the invention, antitumor-active, tumor-specific T cells are prepared by transducing a TCR gene from a tumor-specific CTL into antitumor-active T cells that have been nonspecifically activated, thus enabling tumor-specific cellular immunotherapy to be carried out from even small amounts of blood. MHC class I-restricted, tumor-specific Th cells are obtained by the method, allowing for the production of cells that react with tumor cells expressing an MHC class I molecule and show a helper activity and an antitumor activity.

An objective of the present invention is to provide novel therapeutic agents for cancer, which have an excellent antitumor effect in cancer patients by enhancing their immune function. The present inventors discovered that the administration of at IL-6 inhibitor and/or gemcitabine or a salt thereof to tumor-bearing organisms yields an excellent antitumor T cell response-enhancing effect, and completed the present invention. In addition, the present inventors discovered that the T cell response-enhancing effect produces an excellent antitumor effect.
