A novel treatment for blocking SARS-CoV-2 entry into cells!

Researchers discovered #UNI418, a compound that effectively prevents the penetration of coronavirus. This compound works by regulating dielectric homeostasis, thereby inhibiting the virus's entry into human cells 1/ Image
SARS-CoV-2 enters cells through endocytosis, a process whereby cells absorb material from outside by engulfing it w/ their cell membrane. They demonstrated that inhibiting specific proteins, PIKfyve & PIP5K1C during this process can prevent viral invasion. 2/ Image
Genomic homeostasis is protective system that secures genetic information & allows it to be utilized when needed.
The team established #UNI418 supports genomic homeostasis while simultaneously preventing the infiltration and proliferation of coronaviruses within cells 3/

Image
Existing treatments generally work by inhibiting viral proteins to prevent proliferation, but they are often less effective against mutant strains of the virus. 4/ Image
This study represents the first evidence that #UNI418 can disrupt the virus's infection process, highlighting its potential as a treatment for mutant coronaviruses and other viral infections. 5/ Image
There is a high likelihood that UNI418 can develop into a new treatment paradigm that effectively blocks various viral infections. 6/6

A new study shows that coronavirus spike proteins can trigger mast cell degranulation by binding to cellular receptors and activating the Src/PI3K/AKT signaling pathway, leading to increased calcium levels and mast cell granule release. 1/ Image
The activation and degranulation of mast cells (MCs), triggered by a variety of viruses, are intricately linked to viral pathogenesis. However, the precise mechanism underlying virus-induced MC degranulation remains largely unknown. 2/ Image
In this study, researchers demonstrate the ubiquity of coronavirus-induced MC degranulation and investigate the intracellular signaling pathways that mediate this process. 3/ Image

Tiny RNA molecule may hold the key to treating knee osteoarthritis!

A NEW discovery could pave the way for new breakthroughs in detecting & treating the disease. Researchers identified a circulating microRNA, miR-126-3p, a mechanistic biomarker of osteoarthritis of knee 1/ Image
MiR-126-3p plays a role in reducing blood vessel formation and reducing the severity of knee osteoarthritis, making it not just a signal of disease—but potentially a contributor to it. 2/ Image
Now that scientists are aware of miR-126-3p, they can develop blood tests to detect osteoarthritis of the knee and therapeutics for slowing or even stopping progression. 3/ Image

A new preprint validated earlier findings that genetic factors strongly influence who develops Long COVID, using data from both U.S. (All of Us) and U.K. (Sano GOLD) cohorts with diverse ancestries. 1/ Image
Over 90% of genes identified in the original study were also associated with #LongCOVID in the U.S. population including in Black and Hispanic groups. 2/
These results confirm that combinatorial genetic analysis can uncover more risk genes than traditional Genome-wide association studies (GWAS) and support the continued exploration of drug repurposing candidates for LongCOVID treatment. 3/ Image

A team of researchers has launched a global clinical trial to evaluate two repurposed anti-inflammatory drugs #upadacitinib and #pirfenidone—approved for treating arthritis and lung disease, respectively as potential treatments for #LongCOVID. 1/ Image
he two drugs were selected using artificial intelligence (AI) from over 5,400 proteins linked to LongCOVID, offering a promising shortcut to treatment by targeting 13 shared biological pathways.  2/ Image
Despite the global prevalence of longCOVID, patients report different symptoms & their presentation can be influenced by where they happen to live. 3/ Image

A group from SUNY Buffalo developed a nanoparticle vaccine candidate that displays recombinant H5 and N1 proteins from the highly pathogenic avian influenza H5N1 clade 2.3.4.4b on liposomes. 1/ Image
The widespread transmission of highly pathogenic avian H5N1 influenza, clade 2.3.4.4b, in wild and livestock mammals with isolated human cases has heightened concerns for zoonotic outbreak, necessitating vaccine readiness. 2/ Image
Here, the researchers assess whether recombinant H5 hemagglutinin and N1 neuraminidase proteins can confer protection from disease when antigens are presented as an adjuvanted nanoparticle vaccine. 3/ Image

Children who tested positive for COVID, face significantly higher long-term risks for chronic kidney disease, gastrointestinal disorders, and cardiovascular issues compared to peers who tested negative. 1/ Image
The study, led by the University of Pennsylvania and part of the NIH’s RECOVER initiative, found kidney disease risks increased up to 35%, GI symptoms by up to 28%, and cardiovascular conditions like heart inflammation or arrhythmias by 63%. 2/ Image
Racial differences also emerged with Asian American Pacific Islander children showing slightly higher LongCOVID risk.  3/
