How neurons autonomously regulate their excitability

Posted by in categories: biotech/medical, mobile phones, robotics/AI

Nerve cells can regulate their sensitivity to incoming signals autonomously. A new study led by the University of Bonn has now discovered a mechanism that does just that. The German Center for Neurodegenerative Diseases and the Max Planck Institute for Neurobiology of Behavior were involved in the work. The results have now been published in the journal Cell Reports.

Anyone who has ever sent a voice message with a knows how much the volume matters: Shouting into the microphone results in a distorted and unclear recording. But whispering is not a good idea either—then the result is too quiet and also difficult to understand. That is why sound engineers ensure the perfect sound at every concert and talk show: They regulate each microphone’s gain to match the input signal.

The neurons in the brain can also fine-tune their sensitivity, and even do so autonomously. A new study led by the University of Bonn and the University Hospital Bonn shows how they do this. For this purpose, the participants investigated nerve cell networks that also play a role in vision, hearing and touch. The stimulus first travels to the so-called thalamus, a structure deep in the center of the brain. From there, it is then conducted to the , where it is further processed.

How touch dampens the brain’s response to painful stimuli

Posted by in category: neuroscience

When we press our temples to soothe an aching head or rub an elbow after an unexpected blow, it often brings some relief. It is believed that pain-responsive cells in the brain quiet down when these neurons also receive touch inputs, say scientists at MIT’s McGovern Institute for Brain Research, who for the first time have watched this phenomenon play out in the brains of mice.

The team’s discovery, reported Nov. 6 in the journal Science Advances, offers researchers a deeper understanding of the complicated relationship between pain and touch and could offer some insights into chronic pain in humans.

“We’re interested in this because it’s a common human experience,” says McGovern investigator Fan Wang. “When some part of your body hurts, you rub it, right? We know touch can alleviate pain in this way.” But, she says, the phenomenon has been very difficult for neuroscientists to study.

Measuring Potency of Cell and Gene Therapy Products

Posted by in categories: biotech/medical, genetics

CGT are composed of a diverse group of medicinal products. Cell therapies (including ex vivo gene therapies) involve the transfer of cells with a relevant function into the patient. Cells can have different origins, i.e., human (autologous or allogeneic), different differentiation stages, i.e., stem cells or differentiated cells, and can be genetically modified to exert the intended therapeutic effect. In genetically modified cell therapy, a functional transgene is transfected into cells ex vivo using viral (for example, lentiviruses) or nonviral (e.g., electroporation) vectors. Next, the modified cells are administered to the patient where the transgene will promote a therapeutic effect. Examples of these therapies include chimeric antigen receptor (CAR) T cells and genetically modified human stem cells (HSCs).


This article highlights the importance of measuring potency for cell and gene therapies.

Fasting triggers stem cell regeneration of damaged, old immune system

Posted by in categories: biotech/medical, life extension

Fasting database:

Recreates the immune system;…Prolonged fasting forces the body to use stores of glucose, fat and ketones, but it also breaks down a significant portion of white blood cells. Longo likens the effect to lightening a plane of excess cargo. During each cycle of fasting, this depletion of white blood cells induces changes that trigger stem cell-based regeneration of new immune system cells. In particular, prolonged fasting reduced the enzyme PKA, an effect previously discovered by the Longo team to extend longevity in simple organisms and which has been linked in other research to the regulation of stem cell self-renewal and pluripotency — that is, the potential for one cell to develop into many different cell types. Prolonged fasting also lowered levels of IGF-1, a growth-factor hormone that Longo and others have linked to aging, tumor progression and cancer risk.
