Invariant natural killer T cells might lead to cheaper and more effective immunotherapy.


Researchers at the Imperial College London have discovered that specifically employing invariant natural killer T cells, rather than generic T cells, in cancer immunotherapies based on chimeric antigen receptors might lead to significantly more effective, cheaper, and more easily mass-produced treatments [1].

Abstract

Chimeric antigen receptor anti-CD19 (CAR19)-T cell immunotherapy-induced clinical remissions in CD19+ B cell lymphomas are often short lived. We tested whether CAR19-engineering of the CD1d-restricted invariant natural killer T (iNKT) cells would result in enhanced anti-lymphoma activity. CAR19-iNKT cells co-operatively activated by CD1d- and CAR19-CD19-dependent interactions are more effective than CAR19-T cells against CD1d-expressing lymphomas in vitro and in vivo. The swifter in vivo anti-lymphoma activity of CAR19-iNKT cells and their enhanced ability to eradicate brain lymphomas underpinned an improved tumor-free and overall survival. CD1D transcriptional de-repression by all-trans retinoic acid results in further enhanced cytotoxicity of CAR19-iNKT cells against CD19+ chronic lymphocytic leukemia cells. Thus, iNKT cells are a highly efficient platform for CAR-based immunotherapy of lymphomas and possibly other CD1d-expressing cancers.

“Broadly speaking, a posthuman perspective would call into question the anthropocentric notion that humans are to be privileged over all other forms of life. Posthumanism generally aligns with a more ecological perspective that favors simultaneous coexistence with other species and consideration of the lives and experiences of other species. Posthumanism would thus resist the notion that humans are at the center of any given context and would instead posit that human society is composed of a web of interwoven, entangled relationships of humans, nonhuman animals, organic and inorganic matter, and so on.” https://www.psychologytoday.com/…/conservation-and-compassi… https://paper.li/e-1437691924#/


A new book called “Visualizing Posthuman Conservation in the Age of the Anthropocene” argues against human domination and favors peaceful coexistence with other species.

A novel technique that nudges single atoms to switch places within an atomically thin material could bring scientists another step closer to realizing theoretical physicist Richard Feynman’s vision of building tiny machines from the atom up.

Here at LEAF, we engage in a wide range of activities in support of the development of rejuvenation biotechnology in order to end age-related diseases. We report the latest news in aging research, attend conferences and give talks, educate, advocate, and fundraise for research projects on Lifespan.io; recently, we implemented the Longevity Investor Network in order to bring startup companies and investors together.

The Longevity Investor Network

The Longevity Investor Network is a group of investors who meet every month and invite young biotech companies working on aging to pitch their ideas. A successful pitch can often mean funding for a new startup company, helping to get its product developed and into clinical trials.

The Real Bodies Milan exhibit has officially opened! (https://www.facebook.com/realbodiesworld/) — Honored to have Bioquark Inc.‘s (www.bioquark.com) research on display, with our partners at HealthQE (www.healthqe.cloud), for the coming seven months in the technologies for Immortality section of the exhibit

It is important to know why a program does what it does. This is not a mystery, technology is a tool and that tool is only as good as the human who created it.


You always have to know why a program, makes the decisions that it makes. No program or Algorithm will be perfect, that is the main issue that Lisa Haven brings forward. You also have to make sure of the reason for the error whether it is innocent or intentional or even criminal.

That is the problem when you blindly allow technology to rule the day. Anyone from an old-school management upbringing will tell you, never to allow technology to govern your decisions on its own. You always have to know why, where, and how on your decisions.

It is important to get this kind of technology right. Everyone wants a shortcut, instead of doing the hard work to ensure that information being put forward is correct.

Six years ago, the Voyager 1 spacecraft informed scientists that it had become the first man-made object to enter interstellar space. Now, Voyager 2 has begun to return signs that its own exit from the Solar System could be coming soon.

Two of Voyager 2’s instruments have measured an increase in the number of high-energy particles called cosmic rays hitting the spacecraft, according to a NASA release. Scientists think that the heliosphere, the region of particles and magnetic fields under the Sun’s influence, blocks some cosmic rays. An increase in their rate means that the probe could be nearing the heliopause, the heliosphere’s outer boundary.
