Summary
Type III interferons (IFN-lambda) are novel antiviral cytokines. Their structure, similar to IL-10 but functionally IFN, is reviewed, analyzing isoform differences and potency.
Area of Science:
- Immunology
- Structural Biology
- Virology
Background:
- Type III interferons (IFN-lambda) are a distinct class of cytokines.
- They exhibit antiviral activities via a unique receptor complex.
- IFN-lambda shares structural similarities with the interleukin-10 family.
Purpose of the Study:
- To review the structure of IFN-lambda.
- To examine its relationship with other class II cytokines.
- To analyze structural variations among human IFN-lambda isoforms and their impact on potency.
Main Methods:
- Structural analysis of human IFN-lambda3.
- Comparative review of class II cytokines.
- Isoform-specific structural comparison.
Main Results:
- IFN-lambda possesses structural homology to IL-10 but functions as an interferon.
- Distinct structural features exist between human IFN-lambda isoforms.
- These structural differences correlate with observed variations in biological potency.
Conclusions:
- IFN-lambda represents a unique class of cytokines with dual structural and functional characteristics.
- Understanding IFN-lambda structure is crucial for elucidating its antiviral mechanisms.
- Structural nuances among isoforms dictate their differential potency and biological effects.

01:30Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:25Antibody Structure and Classes
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

00:56Viral Structure
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.
01:26Human Virome
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
