Antimicrobial Proteins01:23

Antimicrobial Proteins

14.9K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

Immune Response Against Viral Pathogens

2.3K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

T Cell Types and Functions01:24

T Cell Types and Functions

3.0K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.7K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

10.2K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Area of Science:

  • Immunology
  • Virology
  • Microbiology

Background:

  • Interferon lambdas (IFN-λs) are cytokines that regulate immune responses by inducing genes.
  • IFN-λs signal through the IFN-λ receptor (IFNLR), activating STAT phosphorylation and downstream gene expression.
  • Unlike IFN-α, IFN-λ signaling exhibits unique characteristics, including variable receptor expression, lower binding affinities, and genetic polymorphisms.

Purpose of the Study:

  • To review the immunobiology of IFN-λs.
  • To explore the role of IFN-λs in viral and bacterial infections.
  • To discuss the clinical implications of IFN-λ signaling and associated genetic variations.

Main Methods:

  • Literature review of recent publications on IFN-λ signaling and its role in infections.
  • Analysis of IFN-λ interactions with its receptor and downstream signaling pathways.
  • Examination of genetic variations (SNPs) within the IFN-λ pathway.

Main Results:

  • IFN-λs play roles in various viral infections (Hepatitis B/C, HTLV-1, rotavirus, influenza) and bacterial infections (Staphylococcus aureus, Mycobacterium tuberculosis).
  • IFN-λ signaling differs from IFN-α signaling in receptor expression, binding affinity, and genetic variations.
  • IFN-λs can act as direct antiviral agents or modulate IFN-α signaling and adaptive immunity.

Conclusions:

  • IFN-λs are critical innate immune cytokines with broad implications for infectious diseases.
  • Understanding IFN-λ immunobiology and genetic variations is crucial for developing novel therapeutics.
  • Further research into IFN-λs may extend beyond viral hepatitis to other infectious and autoimmune conditions.
