Title: Methods of enhancing anti-tumour immunity in a mammal
Inventor: PIZZOFERRATO EVA
IPC: A61K39/00
Filed: 1998-11-25
Abstract: Anti-tumour immune responses are elicited by engineering genetically lymphoma tumour cells to express interleukin- 12 (IL- 12), the combination of B7-1 and interleukin- 12, or by increasing endogenous expression of the costimulatory molecule B7-2. The combination of B7-1 and IL-12 is most effective in minimal disease settings when the tumour cell engineered genetically to express both molecules is inoculated into the same site of tumour burden. In addition, increasing the expression of endogenous B7-2 provides another method by which anti-tumour immunity is generated against unmodified tumour cells. The mechanisms of the anti-tumour immune response are multifactorial involving T cells as well as natural killer (NK) cells.

Filed: 1997-11-13
Abstract: An animal ear tag applicator (1) has a jaw (2) with a pivotal pin (7) which can hold the male part (50) of an animal ear tag and engage it with the female part (51) of the tag held in the lower jaw (3). The jaw (2) is biased by spring (16) to open independently of the handles (4, 5) once the latch (30) has been released. This will only occur after the male and female parts of the tag have been fully engaged. This independent release of the jaw (2) and the ability of the pin (7) to pivot forwardly avoids jamming of the ear tag in the applicator (1), especially when the animal attempts to pull away. The applicator can also be used with single piece tags.
