Cytokines are also targeted by drugs for many diseases such as rheumatoid arthritis, COVID-19, and cancer, but until now, scientists haven’t had a comprehensive view of how different immune cells respond to different cytokines because the immune system is so complex. For many immune-mediated diseases, there's no cure or treatment.
The work appears today in Science. The scientists found a surprising number and diversity of CRISPR systems, including ones that could make edits to DNA in human cells, others that can target RNA, and many with a variety of other functions. They studied several of the new systems in greater detail in the lab.
Durham, North Carolina-based Ribometrix announced a strategic collaboration deal with Genentech , a Roche company, to identify and advance novel RNA-targeted small molecule therapeutics. Targeting RNA is believed to be a way to develop therapeutics for so-called undruggable proteins. The first identifies the 3D RNA motifs.

These factors are converging to enable both identification of novel infectious diseases as well as microbial resistance, before these threats can impact public health, write a team from the European Society for Clinical Microbiology and Infectious Diseases in Frontiers in Science. COVID clearly caught us off guard.
That information led, thanks to vaccine shelved from the first SARS circa 2003, to the rapid development and deployment of mRNA vaccines against the new infectious disease. Seventeen of the entire group (10.7%) had “unanticipated monogenic disease risks (uMDRs).”
Scientists from the Massachusetts Institute of Technology (MIT) and the University of Massachusetts Medical School (UMass), US, have collaborated to create a novel type of nanoparticle that can deliver messenger RNA that encodes for beneficial proteins to the lungs.
The method, described today in Science , provides a way for scientists to learn new details on how translation is regulated within individual cell types and how that changes in disease. By Sarah C.P.

The results were published in Proceedings of National Academy of Sciences of United States of America (PNAS). Through phylogenetic analysis and microscopy techniques, they identified a nuclear-encoded apicoplast RNA polymerase σ subunit called ApSigma. The first identification was based on a bioinformatic analysis.
This is especially true in medicine, where the temporal gap between the initiation of the disease (a random genetic mutation, say) and the appearance of symptoms makes finding the root cause difficult. A capillary shrinks over time – it’s a temporal process – but science is often limited to static snapshots.

There have been several studies that have reported the ability of infectious disease agents to be drug resistant. Infectious agent includes bacteria, virus, fungi, and parasites, and they are capable of causing disease in a living organism. They could be spread by physical contact, airborne, waterborne, foodborne, or vector-borne.
These tough nuts to crack in medical science—biological targets known to play roles in diseases but resistant to traditional drug design—are now seeing new strategies that shift the paradigm from "undruggable" to "druggable." Beyond Proteins: DNA and RNA Frontier The story doesn’t end with proteins.

Instead, this is what is called a splicing mutation; it occurs at the boundary between coding DNA that is read into RNA and protein, and noncoding DNA that is excluded.
This included compiling RNA data, as well as other data points such as patient demographics, clinical treatment arm and patient diagnosis. For years, patients diagnosed with a disease often received the same treatment. And for some people, that treatment worked.
