Predicting naturally occurring viral latency

KLRD1-expressing natural killer cells predict influenza susceptibility We identified KLRD1-expressing NK cells as a potential biomarker for influenza susceptibility. Expression of KLRD1 was inversely correlated with symptom severity. Our results support a model where an early response by KLRD1-expressing NK cells may control influenza infection. The NK cells are natural killer cells that help to control viral latency This was reported as: Scientists discover biomarker for flu susceptibility  “We found that a type of immune cell called a natural killer…

Microbes to humans 2015 Nobel Prize

3 Scientists Win Nobel Prize in Medicine for Parasite-Fighting Therapies Excerpt 1) Success in antimalarial therapy depends on how clever scientists are in using combinations of drugs. Excerpt 2) Dr. Omura played down his accomplishments, saying, “I merely borrowed the power of microbes.” My comment: These two excerpts appear within the context of three paragraphs that clearly link RNA-mediated cell type differentiation in species from microbes to humans. The context attests to what at first may appear to be a…

Domestication via a single amino acid substitution

Evidence That the Origin of Naked Kernels During Maize Domestication Was Caused by a Single Amino Acid Substitution in tga1 Excerpt: “Our molecular and genetic analyses of tga1 show how a simple amino acid change can alter protein function and thereby drive the evolution of a new phenotypic state.” Reported as: Study shows how a kernel got naked and corn became king Excerpt: The answer often lies in mutations, the currency of evolution. Sometimes single letters are changed in the…
