The Tc2 transposon in Caenorhabditis elegans.
A second family of transposons, named Tc2 elements, has been identified in the nematode Caenorhabditis elegans. Tc2 elements are polymorphic in sequence and are present in different numbers in different strains. Like the transposon Tc1, Tc2 is active in the germ line of some C. elegans strains. A high rate of transposition has been observed in the progeny of certain interstrain crosses, where t...
متن کاملTc2 response at the onset of COPD exacerbations.
BACKGROUND T lymphocytes and especially the subpopulations of CD8+ cells are believed to have a key role in COPD pathophysiology, but there are only few data regarding the role of these cells in COPD exacerbation. AIM We aimed to study prospectively changes of CD8+ T-lymphocyte subpopulations in the sputum of COPD patients at the onset of mild exacerbations and at a stable condition in order ...
متن کاملA80G polymorphism of reduced folate carrier 1 (RFC1) and C776G polymorphism of transcobalamin 2 (TC2) genes in Down's syndrome etiology.
CONTEXT AND OBJECTIVE There is evidence that polymorphisms of genes involved in folate metabolism may be associated with higher risk that mothers may bear a Down's syndrome (DS) child. This study therefore had the objective of investigating the A80G polymorphism of the reduced folate carrier 1 (RFC1) gene and the C776G polymorphism of the transcobalamin 2 (TC2) gene as maternal risk factors for...
متن کاملCentral role of Th2/Tc2 lymphocytes in pattern II multiple sclerosis lesions
OBJECTIVE Multiple sclerosis (MS) is a disease of the central nervous system with marked heterogeneity in several aspects including pathological processes. Based on infiltrating immune cells, deposition of humoral factors and loss of oligodendrocytes and/or myelin proteins, four lesion patterns have been described. Pattern II is characterized by antibody and complement deposition in addition to...
متن کاملHuman Tc1 and Tc2/Tc0 CD8 T-cell clones display distinct cell surface and functional phenotypes.
It has recently become clear that distinct subsets of CD8 T cells, analogous to their CD4 counterparts, exist in rodents and humans. To examine functional differences between human CD8 T-cell subsets, we generated Tc1, Tc2, and Tc0 T-cell clones from the peripheral blood of healthy individuals. The majority of CD8 T-cell clones generated displayed a classic Tc1 phenotype, but 10% to 20% secrete...
