Major Funding Announced for Nanobody Research

AgomAb Therapeutics have announced the successful acquisition of a second round of funding ($74M) for research into the applications of antibodies for use in the field of regenerative medicine. Antibodies have already received a large amount of attention for their ability to positively effect numerous conditions such as inflammation, metabolic disorders, and non-healing wounds.

Antibodies are small protein molecules which are used by the body to ‘tag’ foreign pathogens in order for the immune system to identify and destroy them. What is unique about these antibodies is that due to their structure they will only attach themselves to a particular pathogen (at a particular site known as an antigen). In many cases, the binding of an antibody to a pathogen such as a virus is enough to completely inactive the pathogen, making it effectively harmless.

500% Lifespan Increase Achieved in Nematode Worms

Caenorhabditis elegans is a nematode worm which is commonly utilised in longevity research due to their genetic similarity to humans and their extremely short lifespans (often no more than 4 weeks). Previous research into improving the lifespan of these worms has yielded several interesting results, with modifications to their insulin and rapamycin signalling pathways resulting in a 100% and 30% increase in lifespan respectively. These successes prompted the obvious question, what would happen if both of these pathways were modified at the same time?

The Cryonics Industry Would Like to Give You the Past Year, and Many More, Back

When an 87-year-old Californian man was wheeled into an operating room just outside Phoenix last year, the pandemic was at its height and medical protocols were being upended across the country.

A case like his would normally have required 14 or more bags of fluids to be pumped into him, but now that posed a problem.

Had he been infected with the coronavirus, tiny aerosol droplets could have escaped and infected staff, so the operating team had adopted new procedures that reduced the effectiveness of the treatment but used fewer liquids.

‘It’s a wow!’: New CRISPR gene-editing success holds promise for treating many genetic diseases with a single dose

👏😄We are rapidly approaching — from multiple directions of attack (pharmaceutical, nanotechnology, gene manipulation, etc) — the end of all forms of cancer, inherited diseases, even aging itself. It’s a great time to be alive IF you can live long enough to live forever(ish)! Which makes EVERY death that occurs in the meantime to be all the more of a punch to the gut and slap to the face. PARTICULARLY the 600 000 + people here in the US alone! It’s also another reason t… See More.

If the gene-editing tool CRISPR/Cas9 continues to show such promise it will herald a new era for the treatment of many genetic diseases.

Are humans on the brink of achieving immortality?

In August last year, Unity released interim results showing that its drug was probably ineffective in treating study patients suffering from osteoarthritis.

Its stock price plummeted as a consequence, but Dr de Grey remains hopeful that “soon we might have drugs that actively cause these cells to die”.

While Dr de Grey is excited to see much of the life extension research he helped develop come to fruition, some thinkers are raising concerns about the implications of an extended human lifespan.

How Stem Cells Promote the Health of Nearby Cells

Mesenchymal stem cells derived from adipose tissue appear to reverse some effects of aging in nearby somatic cells.

A new study published in the FASEB Journal shows how mesenchymal stem cells derived from adipose tissue (ADSCs) reverse some effects of aging in nearby cells.

It’s not the cells themselves, it’s what they secrete

The original and ongoing main purpose of stem cell therapies is to directly combat stem cell exhaustion: to replenish the body’s regenerative capability by introducing fresh stem cells, which divide into somatic cells in order to repair tissues and organs.

Single bee is making an immortal clone army thanks to a genetic fluke

To understand how the clones can create millions of copies of themselves and yet remain functional, Oldroyd and his team compared the genomes of Cape honeybee workers with those of their queen and her offspring.

After forcing the Cape queen to reproduce asexually by fitting her with surgical tape that prevented her from mating, the team examined certain DNA sequences of both the Cape queen and the 25 larvae she produced. Then, they did the same for four Cape honeybee workers and their 63 larvae.

The team discovered that the asexually reproduced offspring of the queen had levels of recombination (DNA mixing) 100 times greater than the genetically identical cloned offspring of the workers — a finding that suggests the Cape worker bees have evolved a mutation that prevents recombination. Without the risk of a one-third loss of genetic material caused by the asexual reshuffling process, the workers are free to continually create perfect copies of themselves.
