Scientists create special 'telomouse' with human-like telomeres      (via sciencedaily.com)     Original source 

Researchers introduce the 'Telomouse'. By making a subtle genetic alteration in standard lab mice, they've made the mouse telomeres, which protect the chromosome ends, more closely resemble those in humans. The Telomouse model, developed by incorporating a genetic variation from a mouse species with naturally shorter telomeres, provides a valuable resource for in-depth aging and cancer research. This discovery promises to reveal new insights into the genetics of aging and may contribute to enhanced longevity and well-being.

Intestinal bacteria metabolite promotes capture of antigens by dendritic cells      (via sciencedaily.com)     Original source 

Dendritic cells are immune cells that capture and present antigens to T cells, activating an immune response. Researchers have discovered that short-chain fatty acids produced by intestinal bacteria regulate a crucial step in this process, the extension of dendritic 'arms.' This breakthrough finding could potentially lead to the development of disease prevention strategies involving beneficial bacteria and new drugs targeting the regulation of dendritic cell function.

Mammalian cells may consume bacteria-killing viruses to promote cellular health      (via sciencedaily.com)     Original source 

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.

Membrane transporter ensures mobility of sperm cells      (via sciencedaily.com)     Original source 

Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.

Defect in fruit fly respiratory system may provide insights into human aortic aneurysms      (via sciencedaily.com)     Original source 

A team of researchers has gained new insights into the respiratory system of fruit flies -- the so-called tracheal system -- which could be important for future research into aneurysms. Scientists carried out genetic, cell biological and biochemical studies on Drosophila embryos. They found that the cells in the fruit fly's tracheal system are connected to the extracellular matrix by the proteins Dumpy and Piopio.
