Cutaneous reactions in mice injected intradermally with allogeneic cells

An electro-mechanical method for measuring delayed hypersensitivity in mice by increase of ear thickness

An electro-mechanical modification of a micrometer gauge for measurements of mouse ear thickness is described. Its advantages are objectivity and speed of operation. The instrument is useful for measuring delayed hypersensitivity reactions to oxazolone and picryl chloride in mice.

An analysis of the genetic requirements for delayed cutaneous hypersensitivity reactions to transplantation antigens in mice

The experiments reported herein provide ample evidence that mice, like most other mammalian species, are capable of displaying readily observable and reproducible delayed cutaneous hypersensitivity reactions indicative of transplantation immunity. By employing a variety of genetically defined strains, it has been shown that a genetic requirement for the development of a positive normal lymphocyte transfer reaction in mice is a difference between host and cell donor at the H-2 locus. By contrast, the immune lymphocyte transfer reaction consistently reflected the full range of histoincompatibility, both inclusive and exclusive of the H-2. It was incidentally discovered that erythema regularly accompanied delayed cutaneous reactions in the skins of female mice, whereas no local redness accompanied their counterparts in male skins. The influence of cutaneous erythema on the scoring of delayed skin reactions is discussed.
