A significant feature of influenza pandemics is multiple waves of morbidity and mortality over a few months or years. The size of these successive waves depends on intervention strategies including antivirals and vaccination, as well as the effects of immunity gained from previous infection. However, the global vaccine manufacturing capacity is limited. Also, antiviral stockpiles are costly and...
antimicrobial peptides (amps) are extensive group of molecules that produced by variety tissues of invertebrate, plants, and animal species which play an important role in their immunity response. amps have different classifications such as; biosynthetic machines, biological sources, biological functions, molecular properties, covalent bonding patterns, three dimensional structures, and molecul...
UNLABELLED Aspects of intrinsic antiviral immunity are mediated by promyelocytic leukemia nuclear body (PML-NB) constituent proteins. During herpesvirus infection, these antiviral proteins are independently recruited to nuclear domains that contain infecting viral genomes to cooperatively promote viral genome silencing. Central to the execution of this particular antiviral response is the small...
A new study shows that the SARS-CoV-2 nucleocapsid protein represses antiviral type I interferon response through direct interaction with signalling adaptor MAVS. Targeting this process might be a useful therapeutic strategy to boost immunity against COVID-19.
Herpesviruses employ a plethora of mechanisms to circumvent clearance by host immune responses. A key feature of mammalian immune systems is the employment of regulatory pathways that limit immune responsiveness. The primary functions of these mechanisms are to control autoimmunity and limit exuberant responses to harmless antigen in mucosal surfaces. However, such pathways can be exploited by ...
The ability of vaccination to empower natural immune defenses against viral infection is well illustrated by the worldwide eradication of smallpox and the partial elimination of polio after global vaccination efforts (74, 98). Unfortunately, these major successes have been infrequent, and diverse viruses continue to threaten our societies. The development of new vaccines, or the improvement of ...
Homology-dependent RNA silencing occurs in many eukaryotic cells. We reported recently that nodaviral infection triggers an RNA silencing-based antiviral response (RSAR) in Drosophila, which is capable of a rapid virus clearance in the absence of expression of a virus-encoded suppressor. Here, we present further evidence to show that the Drosophila RSAR is mediated by the RNA interference (RNAi...
Intrinsic immune responses autonomously inhibit viral replication and spread. One pathway that restricts viral infection in plants and insects is RNA interference (RNAi), which targets and degrades viral RNA to limit infection. To identify additional genes involved in intrinsic antiviral immunity, we screened Drosophila cells for modulators of viral infection using an RNAi library. We identifie...
The red swamp crayfish (Procambarus clarkii) is one of the most economically important farmed aquatic species in China. Compared with its relatively well-known antibacterial and antifungal mechanisms, the antiviral mechanism is still unclear. We used Illumina-based RNA sequencing and bioinformatic technology to obtain high-quality sequence reads from the crayfish lymph organ. A total of 5933 di...
Double-stranded RNA (dsRNA) is a common by-product of viral infections and acts as a potent trigger of antiviral immunity. In the nematode C. elegans, sid-1 encodes a dsRNA transporter that is highly conserved throughout animal evolution, but the physiological role of SID-1 and its orthologs remains unclear. Here, we show that the mammalian SID-1 ortholog, SIDT2, is required to transport intern...
