Sense of touch and heat research wins Nobel Prize! The winners explained how our bodies convert physical sensations into electrical messages in the nervous system. Their findings could lead to new ways of treating pain. This could be an interesting link with the mechanisms of how acupuncture and moxibustion work! https://www.nobelprize.org/prizes/medicine/2021/summary/

The groundbreaking discoveries of the TRPV1, TRPM8 and Piezo channels by this year’s Nobel Prize laureates David Julius and Ardem Patapoutian have allowed us to understand how heat, cold and mechanical force can initiate the nerve impulses that allow us to perceive and adapt to the world around us.

The TRP channels are central for our ability to perceive temperature. The Piezo2 channel endows us with the sense of touch and the ability to feel the position and movement of our body parts. TRP and Piezo channels also contribute to numerous additional physiological functions that depend on sensing temperature or mechanical stimuli. Intensive ongoing research originating from this year’s Nobel Prize awarded discoveries focuses on elucidating their functions in a variety of physiological processes. This knowledge is being used to develop treatments for a wide range of disease conditions, including chronic pain.

The 2021 Nobel Prize in Physiology or Medicine has been awarded jointly to David Julius and Ardem Patapoutian “for their discoveries of receptors for temperature and touch.”

Hooray for hands 🙌 🙏

The Nobel Prize research awarded on October 4th, 2021 is very supportive of our work. Be sure to read the full press release information and the advanced information (links below) as it goes into the detail of explaining the molecular basis for sensing heat, cold and mechanical force, which is fundamental for our ability to feel, interpret and interact with our internal and external environment.

Summary: They discovered a class of sensors via pressure- sensitive cells that respond to mechanical stimuli in the skin and internal organs.

Ardem Patapoutian, awarded the 2021 Nobel Prize in Physiology or Medicine, used pressure-sensitive cells to discover a novel class of sensors that respond to mechanical stimuli in the skin and internal organs.

Patapoutian and his collaborators first identified a cell line that gave off a measurable electric signal when individual cells were poked with a micropipette. It was assumed that the receptor activated by mechanical force is an ion channel and in a next step 72 candidate genes encoding possible receptors were identified. These genes were inactivated one by one to discover the gene responsible for mechanosensitivity in the studied cells. After an arduous search, Patapoutian and his co-workers succeeded in identifying a single gene whose silencing rendered the cells insensitive to poking with the micropipette. A new and entirely unknown mechanosensitive ion channel had been discovered and was given the name Piezo1, after the Greek word for pressure. Through its similarity to Piezo1, a second gene was discovered and named Piezo2. Sensory neurons were found to express high levels of Piezo2 and further studies firmly established that Piezo1 and Piezo2 are ion channels that are directly activated by the exertion of pressure on cell membranes.

The breakthrough by Patapoutian led to a series of papers from his and other groups, demonstrating that the Piezo2 ion channel is essential for the sense of touch. Moreover, Piezo2 was shown to play a key role in the critically important sensing of body position and motion, known as proprioception. In further work, Piezo1 and Piezo2 channels have been shown to regulate additional important physiological processes including blood pressure, respiration and urinary bladder control.

Ireland has the highest case rate in the world... the latest testing showed 42 out of 92 new samples were positive for the variant — so nearly half.
We in the U.S. are about to see a lot more cases of a more deadly variant.

Jeg har dækket corona siden begyndelsen. Lige nu er jeg mere bange, end jeg har været siden marts Den nye variant breder sig i ly af gode smittetal. Imens er vi ved at løbe tør for nye restriktioner

our lifestyles need to support our bodies most efficient functionality:

When We Eat, or Don’t Eat, May Be Critical for Health A growing body of research suggests that our bodies function optimally when we align our eating patterns with our circadian rhythms.

Specific areas of the brain can change what they are doing, and communication within the brain is key.

The results clarify earlier conflicting findings on the role of specific brain regions, such as the insula, in guiding antisocial and psychopathic behavior, and may shed light on how to encourage altruistic behavior in humans.

Chatter in the deep brain spurs empathy in rats: Communication within the brain is key to empathetic decision-making By combining electrical monitoring of neural activity with machine learning, a team of neuroscientists has tuned into the brain chatter of rats engaged in helping other rats. The results clarify earlier conflicting findings on the role of specific brain regions, such as the insula, in guiding antiso...
