Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...ce genes is painting a picture of how the parasite escapes destruction by most of the agents now used against it, he said., When a malaria parasite is transmitted through a mosquito bite, the mosquito injects the parasite into skin or blood, which then travels to the liver within minutes, grows and divi...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

... studies provide important clues about how anthrax escapes the immune system during infection," said Nick Duesbery, Ph.D. deputy director for research operations and senior scientific investigator at the Van Andel Institute in Grand Rapids, Mich. In 1998, Duesbery discovered that the toxin interrupts the ...

Extraordinary life found around deep-sea gas seeps

...he seafloor where methane gas or hydrogen sulphide escapes from large stores deep below. Like hydrothermal vents, cold seeps support unique communities of animals living in symbiosis with microbes that can convert these energy-rich chemicals to living matter (a form of 'chemosynthesis') in the absence of sun...

Pitt professor's theory of evolution gets boost from cell research

...ferent environment by the time the novelty finally escapes its recessive state and expresses itself. "You just can't do a quick fix on the environment to prevent extinction because the cause of the mutation occurred some time in the past, and you don't know what the cause of the stress was at that time," Sc...

UCLA scientists discover immune response to HIV differs, even in identical twins

...ceptors on their surface, killing the invader. HIV escapes this action by changing shape so that it does not fit into those receptors. "These boys are as similar as two humans can be, yet we see differences in how they fight the virus," said Dr. Paul Krogstad, professor of pediatrics and pharmacology, and ...

Chlamydia parasite lives off our fat

... an example of 'organelle mimicry' where Chlamydia escapes recognition by the host by cloaking itself in these fat-rich structures." Understanding host lipid transport by Chlamydiae may have further implication for chronic infections, the researchers say. For example, lipid-rich macrophages ("foam cells") ...

Polymer gel can block toxic leakage problem in gene therapy

...e from the injection needle. Yuan said such viral escapes are inevitable since the needle's diameter is 30 times larger than the width of the microvessels that supply the tumor with blood. The needle is also wider than the spaces between each of those vessels, he added. The first author of the British Jour...
