T Memory Cells: Quality not Quantity
Immunological memory to pathogens is associated with clonal expansion and heightened responsiveness of antigen-specific T cells. Recent work emphasizes that, for efficient protective immunity, qualitative changes in T memory cells are vitally important.
متن کاملMemory formation under stress: quantity and quality.
Stress shapes memory. Depending on the timing of the stress exposure facilitating and impairing effects of stress are reported on how much is learned and remembered. Beyond such stress-induced changes in the quantity of memory, recent research suggests that stress also affects the contribution of multiple memory systems to performance. Under stress, rigid 'habit' memory gets favored over more f...
متن کاملQuality not quantity: the pufferfish genome.
The genome of the pufferfish, Fugu rubripes (Fugu) is compact. With a similar gene complement to mammals and a genome size of just 400 Mb, gene density is high averaging one every 6-7 kb. Initial characterization of this genome has shown that although genes are much smaller and more densely spaced, their intron/exon structure is conserved with the resulting introns being small. There is little ...
متن کاملQuantity, not quality: the relationship between fluid intelligence and working memory capacity.
A key motivation for understanding capacity in working memory (WM) is its relationship with fluid intelligence. Recent evidence has suggested a two-factor model that distinguishes between the number of representations that can be maintained in WM and the resolution of those representations. To determine how these factors relate to fluid intelligence, we conducted an exploratory factor analysis ...
متن کاملQuantity, not quality, of antibody response decreased in the elderly.
The burden of disease during seasonal influenza epidemics is felt most keenly among the very young and the elderly. Although vaccination effectively protects children and young adults against infection, it has limited efficacy in elderly individuals. This has been linked to a reduced ability to induce a robust serum antibody response. In this issue of the JCI, Sasaki et al. identify some of the...
