From being a promising yet underexplored approach in the 1990s, mRNA therapeutics have evolved dramatically. The discovery of chemical modifications to overcome mRNA’s instability and immunotoxicity enabled these therapeutics to reach clinical trials and the forefront of modern medicine. The platform’s scalability, rapid production and relatively straightforward manufacturing process mean that mRNA therapeutics are a powerful alternative to traditional small molecule drugs and DNA technology.

Enzymes are a vital tool that make in vitro transcription possible and refine the reaction products to generate highly pure, homogeneous mRNA. In this ebook, we provide an in-depth review into:

Experimental findings indicated that activating T cells for 48 hours in combination of certain stimuli could encourage aerobic glycolysis. The highest level of aerobic glycolysis was noted with a combination of three stimuli, namely T cell receptor (TCR) triggering, CD28 costimulation, and hyper-physiologic concentrations of IL-2.

To generate an ‘‘in vivo-activated’’-like state and enhance efficacy, freshly isolated TCR-Tg pmel-1 CD8+ T cells were activated using antigen-presenting cells, cognate peptide (gp100), and IL-2. A 7-day T cell conditioning with DCA reduced extracellular lactate and increased total acetyl-coenzyme A (CoA) by changing glycolytic flux.

To assess the effects of DCA conditioning on the potency of therapeutic T cells in cancer immunotherapy, these cells were used to treat mice bearing B16 melanoma. Cytotoxicity assays showed a small but significant improvement in the therapeutic potential of DCA-conditioned T cells.

We often discuss cybernetic, genetic engineering, artificial intelligence, and hybrids of them, but what truly is synthetic life? And what is it like?

All we are made of comes from dying stars, those rare supernovae and other cosmic death throes that forge those scarce heavier elements, but could we learn true alchemy and mass manufacture those materials ourselves, and even others not found in nature?

According to recent arguments for panpsychism, all (or most) physical properties are dispositional, dispositions require categorical grounds, and the only categorical properties we know are phenomenal properties. Therefore, phenomenal properties can be posited as the categorical grounds of all (or most) physical properties—in order to solve the mind–body problem and/or in order avoid noumenalism about the grounds of the physical world. One challenge to this case comes from dispositionalism, which agrees that all physical properties are dispositional, but denies that dispositions require categorical grounds. In this paper, I propose that this challenge can be met by the claim that the only (fundamentally) dispositional properties we know are phenomenal properties, in particular, phenomenal properties associated with agency, intention and/or motivation.
