Research shows NPD1 protects a key component of vision
.... RPE cells are responsible for the renewal of the tips of photoreceptor cells (rods and cones) crucial to vision. Neuroprotectin D1 is a messenger (mediator) discovered by Nicolas Bazan, MD, PhD, Boyd Professor, Ernest C. and Yvette C. Villere Professor of Ophthalmology, and Director of the Neuroscienc...Californians urged to help reduce spread of Sudden Oak Death

...pe, they watched the cell membrane move toward the tips of the microvilli and pop off the ends in the form of vesicles, tiny bubble-like packets. Their findings, reported in the May 21 Journal of Cell Biology with one of their images featured on the issue cover, have implications for nutrient processing a...Newborn neurons like to hang with the 'in' crowd
...i. However, as the new neurons matured, the tiny tips filled out and started to monopolize the synaptic connections. "That's what we believe is the crux of the study: the survival of new neurons may depend on the ability to compete out the older existing neurons," says Gage. Earlier studies had shown th......h cones." These are specialized structures at the tips of growing nerve fibers, called axons, which sense guidance signals in their environment and "steer" the axons. Cell movement also requires polarization to position the cell and help navigate its movement. Polarization is characterized by formation...Scripps research team sheds light on long-sought cold sensation gene

When opened, ions flowing through TRPM8 lead to the activation of the sensory neuron, which in turn sends a signal to the brain.

... 1 Telomeres have been compared with the plastic tips on shoelaces because they prevent chromosome ends from fraying and sticking to each other, which would otherwise result in genomic instability. Telomeres are also thought to be the "clock" that regulates how many times an individual cell can divide. ...Cancer cells forming blood vessels send their copper to the edge
...etween 80 and 90 percent of cellular copper to the tips of the tendril-like projections angiogenic cells send out between one another and across the cellular membrane within the first two hours." Copper did, indeed, appear to play a special role in angiogenesis, at least on the basis of this observation. ...Shortening chromosomes cause for earlier cancer onset in families with rare syndrome
... Telomeres are repeated sequences of DNA at the tips of every chromosome that function as a sort of genetic slack. As cells grow and divide throughout life, the chromosomes, which contain all of an individuals genetic information, replicate as well. The enzymes that create copies of chromosomes cannot,...DNA ends: Common tool, different job

After about 60 divisions, the telomeres are eroded away to the point that the cell stops dividing.
