5' terminal nucleotide determines the immunogenicity of IVT RNAs.

In vitro transcription (IVT) is a technology of vital importance that facilitated the production of mRNA therapeutics and drove numerous breakthroughs in RNA biology. T7 polymerase-produced RNAs can begin with either 5'-triphosphate guanosine (5'-pppG) or 5'-triphosphate adenosine (5'-pppA), generating potential agonists for the RIG-I/type I interferon response. While it is established that IVT can yield highly immunogenic double-stranded RNA (dsRNA) via promoterless transcription, the specific contribution of initiating nucleosides to this process has not been previously reported.

Identification of Novel Therapeutic Candidates Against SARS-CoV-2 Infections: An Application of RNA Sequencing Toward mRNA Based Nanotherapeutics.

Due to fast transmission and various circulating SARS-CoV-2 variants, a significant increase of coronavirus 2019 infection cases with acute respiratory symptoms has prompted worries about the efficiency of current vaccines. The possible evasion from vaccine immunity urged scientists to identify novel therapeutic targets for developing improved vaccines to manage worldwide COVID-19 infections. Our study sequenced pooled peripheral blood mononuclear cells transcriptomes of SARS-CoV-2 patients with moderate and critical clinical outcomes to identify novel potential host receptors and biomarkers that can assist in developing new translational nanomedicines and vaccine therapies.

IgNAR antibody: Structural features, diversity and applications.

In response to the invasion of exogenous microorganisms, one of the defence strategies of the immune system is to produce antibodies. Cartilaginous fish is among those who evolved the earliest humoral immune system that utilizes immunoglobulin-type antibodies. The cartilaginous fish antibodies fall into three categories: IgW, IgM, and IgNAR.

The current status of anti-GPCR drugs against different cancers.

G protein coupled receptors (GPCRs) have emerged as the most potential target for a number of drug discovery programs ranging from control of blood pressure, diabetes, cure for genetic diseases to treatment of cancer. A panel of different ligands including hormones, peptides, ions and small molecules is responsible for activation of these receptors. Molecular genetics has identified key GPCRs, whose mutations or altered expressions are linked with tumorgenicity.

Repeatedly heated mix vegetable oils-induced atherosclerosis and effects of Murraya koenigii.

Background: Statins are considered as standard drugs to control cholesterol levels, but their use is also associated with renal hypertrophy, hemorrhagic stroke, hepatomegaly, and myopathy. Murraya koenigii is an herb that is used in traditional cuisine and as a medicine in South Asia. Here we assessed the antidyslipidemic and antiatherosclerotic effects of this spice in repeated heated mix vegetable oils (RHMVO)-induced atherosclerotic models.

Chromosomal region 1q24.1 is associated with increased risk of schizophrenia in Pakistani population.

Schizophrenia is a stressful, chronic and in many cases incorrigible psychological disorder. Till now no biomarker is available for diagnosis of this condition and diagnosis is done purely on psychiatric bases. A strong genetic association of human genome region 1q24.

Expression of SOCS1 and SOCS3 Genes in Interferon-Treated and Direct-Acting Antiviral Drugs-Treated Hepatitis C Patients.

Genetics of host plays a significant role in susceptibility and pathogenesis of disease. During hepatitis C virus (HCV) infection, HCV proteins interfere with interferon (IFN) signaling pathways and upregulate transcription of suppressor of cytokine signaling 1 and 3 genes (SOCS1 and SOCS3), which results in impaired immune response. In this study, we evaluated relative expression of SOCS1 and SOCS3 in untreated HCV patients and patients treated with 2 different treatment strategies that are, (IFN therapy and direct-acting antiviral (DAA) drug regimen.

Unexpected Response Profiles Seen in Hepatitis C Virus-Infected Patients Treated with Sofosbuvir Plus Ribavirin: Five Case Reports.

Direct-acting antivirals (DAAs) have been proved as potent agents in the new era of Hepatitis C therapeutics. DAA has evolved to prove highly efficacious treatment rates and sustained virological response in hepatitis C virus (HCV)-treated patients and has shown minimal side effects, but in this study, we reported five cases that showed unusual response toward the use of DAA. The diagnosis was an unusual response of abruptly high viral titers and liver function tests (LFTs) in patients who received DAA combination therapy.

Therapeutic Strategies of Clustered Regularly Interspaced Palindromic Repeats-Cas Systems for Different Viral Infections.

The clustered regularly interspaced palindromic repeats (CRISPR)/Cas systems have rapidly transitioned from intriguing prokaryotic defense systems to an efficient therapeutic tool. This cutting-edge technology is currently revolutionizing to combat hostile viruses because of its reproducibility, high potency, ease of use, limited off-target activity, and development of quick immune response against viruses. CRISPR gene editing technology eliminates the virus by breaking the DNA that ultimately halts viral replication.
