Huntington's disease (HD) is one of an increasing number of neurodegenerative disorders caused by a CAG/polyglutamine repeat expansion. Mice have been generated that are transgenic for the 5' end of the human HD gene carrying (CAG)115-(CAG)150 repeat expansions. In three lines, the transgene is ubiquitously expressed at both mRNA and protein level.… (More)
Analysis of HLA class II transgenic mice has progressed in recent years from analysis of single chain HLA class II transgenes with expression of mixed mouse/human heterodimers to double transgenic mice expressing normal human heterodimers. Previous studies have used either HLA transgenic mice in which there is a species-matched interaction with CD4 or mice… (More)
The rectal temperature of 8 marmosets was taken regularly throughout a 76 hour period. A pronounced circadian rhythm was detected: body temperature reached a maximum during the light phase and a minimum during the dark phase.
The ability of female mice to rapidly reject syngenic male skin grafts is largely determined by dominant genes in the IB region of the H-2b halotype, whereas the ability to produce anti-H-Y cytotoxic cells is determined by a dominant gene in the IA region the H-2b halotype, or by complementary genes in the IC region of some other haplotypes. Thus, it seems… (More)
Cross-reactive T-cell cytotoxicity is seen when cytotoxic responses are generated in mixed lymphocyte cultures either between mouse strans which differ at the major histocompatibility complex, H-2, or between H-2b mutant strains and the strain from which they were derived. This cross-reactivity can be measured with [51Cr] labeled target cells from a number… (More)
The puffer fish ( Fugu rubripes ) has a compact genome of 400 Mbp which is approximately 7.5-fold smaller than the human genome. It contains a similar number of genes but is deficient in intergenic, intronic and dispersed repetitive sequences. Fugu is becoming established as the model vertebrate genome for the identification and characterisation of novel… (More)
All adult marmosets tested had ureaplasmas in their throats but not in the lower respiratory tract, and rarely in the genital tract. Ureaplasmas persisted in the throat of a marmoset separated from the colony for 44 days. They could not be recovered from the animals for at least nine weeks after a course of minocycline. Airborne reinfection did not occur… (More)
