T cells support long-lived antibody-producing cells

Posted by in category: biotech/medical

If you’ve ever wondered how a vaccine given decades ago can still protect against infection, you have your plasma cells to thank. Plasma cells are long-lived B cells that reside in the bone marrow and churn out antibodies against previously encountered vaccines or pathogens.

While are vital components of the immune system, they can also be a contributor to disease, as is the case in autoimmune diseases, such as lupus and rheumatoid arthritis, and in certain cancers, such as multiple myeloma.

Now, a group led by researchers at the University of Pennsylvania School of Veterinary Medicine, has come to a better understanding of how these cells are maintained. Using a specialized type of microscope that captures the movement and interaction of cells in , the scientists observed that, in the , immune cells called regulatory T cells closely interact with plasma cells and support them. When the T cells aren’t there, plasma cells vanish.

The record lifespan of 122 years could be surpassed via innovative medicine

Posted by in categories: biotech/medical, life extension, neuroscience

We celebrate her birthday and life but what fun is there to living so long when aging takes its toll? Science is aiming to do better, find out how here!


Today, February 21, is the birthday of Jeanne Louise Calment – the oldest verified human being ever, who managed to live an amazing 122 years and 164 days!

Jeanne was an independent and positive person, and she managed to live all alone until aged 110. After a fire in her apartment she moved into a nursing home, but even there she was still able to take care of herself. However, shortly before her 115th birthday she fell down a stairway and never fully recovered her ability to walk.

Genetically-engineered hens produce birds of a different feather

Posted by in categories: bioengineering, biotech/medical, genetics

Rare breeds of chickens could soon come from entirely different types of hens. The University of Edinburgh’s Roslin Institute with help from US biotechnology company Recombinetics used gene editing techniques to create surrogate hens that grow up to produce eggs with all the genetic information of different breeds.

We’ve seen gene editing and transfer techniques used to create better yeast, bigger trees and even glowing pigs, among numerous other examples, but this is believed to be the first gene-edited bird to come out of Europe.

The team used a gene editing tool called TALEN (for transcription activator-like effector nucleases), which is similar to the more widely publicized CRISPR/Cas9, to delete part of a chicken gene called DDX4 that is related to fertility. Hens with this modification did not produce eggs but were healthy in all other ways.

Our society has never aged more rapidly – one of the most visible symptoms of the changing demographics is the exponential increase in the incidence of age-related diseases, including cancer, cardiovascular diseases and osteoarthritis. Not only does aging have a negative effect on the quality of life among the elderly but it also causes a significant financial strain on both private and public sectors. As the proportion of older people is increasing so is health care spending. According to a WHO analysis, the annual number of new cancer cases is projected to rise to 17 million by 2020, and reach 27 million by 2030. Similar trends are clearly visible in other age-related diseases such as cardiovascular disease. Few effective treatments addressing these challenges are currently available and most of them focus on a single disease rather than adopting a more holistic approach to aging.

The Next Pseudoscience Health Craze Is All About Genetics

Posted by in categories: biotech/medical, food, genetics, health

Husar, a 38-year-old telecom salesman, had spent most of his life eating the sort of Eastern European fare typical of his native Ukraine: lots of meat, potatoes, salt and saturated fats. DNA Lifestyle Coach suggested his body might appreciate a more Mediterranean diet instead.


Recently, Vitaliy Husar received results from a DNA screening that changed his life. It wasn’t a gene that suggested a high likelihood of cancer or a shocking revelation about his family tree. It was his diet. It was all wrong.

How Bill and Melinda Gates helped save 122m lives – and what they want to solve next

Posted by in category: biotech/medical

But between the jokes is the data. Bill and Melinda Gates sum up what has been achieved with their combined billions over the past decade in a series of big numbers, and end with the hope of reaching the magic zero – no more disease.


In letter to philanthropic partner Warren Buffett, the Gates define achievements from vaccines to lives saved – while still pushing for gains in infant mortality.
