To treat Ebola virus infections, researchers are taking a close look at a key piece of the virus: polymerase. Polymerase is a viral protein that directs how Ebola virus replicates its genome as it infects new hosts. Drugs that target polymerase could potentially treat Ebola virus infections and save lives.

Targeted drug treatment leads tumor cells to imitate viral infection By Ari Navetta July 11, 2024 Breadcrumb Home Targeted drug treatment leads tumor cells to imitate viral infection Exploiting "viral mimicry," mIDH1 inhibitors trick tumors into thinking they are infected with a virus.
The complex relationship between a virus and its host is one of the hottest topics in science right now, and has been given considerable attention in recent weeks as a result of the race to understand the virus that causes COVID-19 and its potential vulnerabilities.
Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. The novel, hairpin-shaped molecule was named cabRNA for CBASS-activating bacteriophage RNA.
Introduction Messenger RNA (mRNA) technology has emerged as one of the most significant medical breakthroughs. This approach can be personalized for each patient by sequencing the tumor's DNA and RNA to identify unique mutations. One of the most promising mRNA applications in this field is protein replacement therapy.
(Nasdaq:BCRX) today announced that data from part 1 of a clinical trial of its broad-spectrum antiviral, galidesivir, showed that galidesivir was safe and generally well tolerated in patients infected with SARS-CoV-2, the virus that causes COVID-19. It is in advanced development for the treatment of Marburg virus disease.
A range of companies are exploring potential gene editing therapies based on a CRISPR-Cas9 system, and the ability to tune the CRISPR cut could prevent off-target editing or control the degree of a target protein’s production. The authors found that tracr-L redirects Cas9 in S. The authors suggest natural tracr-L regulates autoimmunity.
After some time in that role and launching several products, I received a call from Bill Banyai and Bill Peck, or ‘The Bills’ as we call them, who were building a company around technology that creates DNA by ‘writing’ it on a silicon chip. These are synthetic, not the live virus, so do not pose a risk of infection.

Clover expects to produce hundreds of millions of vaccine doses in 2021 and up to 1 billion vaccine doses in peak annual production as required by global demand. Similar to other enveloped RNA viruses such as HIV, RSV and Influenza, SARS-CoV-2 is also an RNAvirus that has a trimeric spike (S) protein on its viral envelope.
During challenge with the original SARS-CoV-2 virus, animals vaccinated with CV2CoV were found to be better protected based on highly effective clearance of the virus in the lungs and nasal passages. Clearance of the virus in the lungs and nasal passages of the animals was tested following challenge infection with the original virus.
In sickle cell disease, for instance, a missense mutation in the HBB gene , encoding the beta-globin subunit of hemoglobin, leads to the production of abnormal hemoglobin S. Gene therapy strategies targeting oncogene inactivation, such as RNA interference and gene-editing technologies, have shown promise in preclinical and clinical studies.
TLR7-9 are among the set that are endosomally located and respond to single-stranded RNA (TLR7and TLR8) or unmethylated single-stranded DNA containing cytosine-phosphate-guanine (CpG) motifs (TLR9). Toll/IL-1 receptor family members are important regulators of inflammation and host resistance. Nature Immunol., 11:373-384 (2010)).
Cabotegravir is a ViiV product marketed as Cabenuva, and rilpivirine is a Janssen product with a brand name Edurant. While much more remains to be done to make HIV history, today’s milestone reminds us how far medical innovation has come since the first reported cases of the virus almost 40 years ago.”.

In the study, immunization with the hAd5-COVID-19 vaccine inhibited SARS-CoV-2 virus replication in 100% (10 of 10) of Rhesus macaques, with a drop in viral replication starting on the first day of vaccine administration, and undetectable viral levels as early as three to five days post-challenge in most of the animals.
Immunization of non-human primates (rhesus macaques) with BNT162b2, a nucleoside-modified messenger RNA (modRNA) candidate that expresses the SARS-CoV-2 spike glycoprotein, resulted in strong anti-viral effects against an infectious SARS-CoV-2 challenge.

Infectious agent includes bacteria, virus, fungi, and parasites, and they are capable of causing disease in a living organism. Studies have shown that targeting some expression gene sites could lead to the production of new drugs as indicated. They could be spread by physical contact, airborne, waterborne, foodborne, or vector-borne.
RNA-based therapies, including mRNA and RNA interference (RNAi), are being explored to modulate gene expression in heart cells. For instance, mRNA therapies can promote the production of specific proteins required for heart tissue repair, while RNAi can silence harmful gene expression, such as those driving fibrosis in heart failure.
