Ion Channel Makes African Naked Mole-Rat Insensitive To Acid-Induced Pain
2011-12-21 04:54:27

Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world’s most unusual mammals, feels no pain when exposed to acid.

Drawing on X-ray crystallography and experimental data, as well as a software suite for predicting and designing protein structures, a UC Davis School of Medicine researcher has developed an algorithm that predicts what has been impossible to generate in the laboratory: the conformational changes in voltage-gated sodium channels when they are at rest or actively transmitting a signal in muscle and nerve cells.

The most poisonous substance on Earth — already used medically in small doses to treat certain nerve disorders and facial wrinkles — could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting.

Brain Makes Memories Rhythmically

The brain learns through changes in the strength of its synapses -- the connections between neurons -- in response to stimuli.

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials.

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current.

Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body (input), and axons carry signals away (output).

New research from the University of North Carolina at Chapel Hill School of Medicine describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses.
