Telomeres in most somatic cells shorten with each cell division, and critically short telomeres lead to cellular dysfunction, cell cycle arrest, and senescence. Thus, telomere shortening is an important hallmark of human cellular senescence. Quantitative fluorescence in situ hybridization (Q-FISH) using formalin-fixed paraffin-embedded (FFPE) tissue sections allows the estimation of telomere lengths in individual cells in histological sections.

There are currently no standard methods for diagnosing cardiac diseases in dolphins. These diseases may consequently be overlooked and go undiagnosed. The presence and severity of cardiac diseases in humans can be determined using blood tests.

Article Synopsis
  • Aging affects stem cells, leading to decreased function and impacting tissue health, but hematopoietic stem cells (HSCs) develop a resilience that helps them survive.* -
  • Old HSCs shift their metabolism by activating the pentose phosphate pathway, allowing them to resist oxidative stress and operate independently of glycolysis.* -
  • The study reveals that old HSCs enhance energy production through mitochondrial changes, aided by increased levels of a specific factor (SDHAF1), improving their survival during stress and addressing age-related blood cell formation issues.*

Inhibitory natural killer (NK) cell receptors recognize MHC class I (MHC-I) in on target cells and suppress cytotoxicity. Some NK cell receptors recognize MHC-I in , but the role of this interaction is uncertain. Ly49Q, an atypical Ly49 receptor expressed in non-NK cells, binds MHC-I in and mediates chemotaxis of neutrophils and type I interferon production by plasmacytoid dendritic cells.
