The inflammatory bowel diseases (IBD); Crohn’s and Ulcerative colitis, result from an altered host response to intestinal flora. Recurrent inflammation with ulceration and tissue restitution confers an increased risk of cancer in both UC and Crohns, and genome wide searches have identified a number of disease susceptibility alleles. The carcinogenesis pathway in colitis-associated colorectal cancer...
Recently, Quyn et al. demonstrated that cells within the stem cell zone of human and mouse intestinal crypts tend to align their mitotic spindles perpendicular to the basal membrane of the crypt. This is associated with asymmetric division, whereby particular proteins and individual chromatids are preferentially segregated to one daughter cell. In colonic mucosa containing a heterozygous adenomatous...
The concept of experimental allergic encephalomyelitis (EAE) being linked to both rabies post-vaccination encephalomyelitis and multiple sclerosis (MS) has raised the intriguing question whether animal studies carried out for the induction and transmission of transmissible spongiform encephalopathies (TSEs) using brain antigens including prions do have a similar immunopathogenetic mechanism. Although...
