Insights

Histo-blood group antigens (HBGAs) influence rotavirus gastroenteritis susceptibility in children. Secretor-positive individuals and those with blood groups A or AB are more prone to symptomatic rotavirus P[8] infections.

Area of Science:

  • Virology
  • Immunology
  • Genetics

Background:

  • Group A rotaviruses are a leading cause of acute gastroenteritis in children globally.
  • Rotavirus genotype prevalence varies geographically and is associated with human histo-blood group antigens (HBGAs).

Purpose of the Study:

  • To investigate the association between HBGA profiles and rotavirus gastroenteritis in children in Valencia, Spain.
  • To determine the role of secretor status, ABO blood group, and Lewis antigens in rotavirus infection susceptibility.

Main Methods:

  • Collected stool and saliva samples from 133 children with rotavirus infection (2013-2015).
  • Determined infecting rotavirus genotypes and HBGA phenotypes (secretor status, ABO, Lewis antigens).
  • Compared patient data with control groups and blood donor data.

Main Results:

  • Rotavirus G9P[8] was the most common strain (49.6%), followed by G1P[8] (20.3%) and G12P[8] (14.3%).
  • Infected children were predominantly secretor-positive (99%) and Lewis b positive (91.7%).
  • Children with blood group A and AB showed significantly higher susceptibility to rotavirus gastroenteritis compared to blood group O.

Conclusions:

  • A specific HBGA genetic background is linked to rotavirus P[8] susceptibility.
  • Symptomatic rotavirus P[8] infection is more frequent in secretor-positive (FUT2+) individuals.
  • No significant differences in susceptibility were found between rotavirus G genotypes based on HBGA profiles.

Antigen Presenting Cells

The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Antigen Processing Pathways01:31

Antigen Processing Pathways

MHC molecules are key players in the immune response, enabling T cells to recognize and respond to specific antigens. They are present on the surface of all nucleated cells in the body and are instrumental in presenting antigens to T cells and activating them. T cells recognize the MHC-antigen complex and initiate an immune response. MHC class I and MHC class II are two main types of MHC molecules, each associated with a distinct antigen processing pathway.

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
