Resumen

Los virus rompen barreras especializadas de tejido sanguíneo (BTB), como la barrera hematoencefálica (BBB), para causar enfermedades. Comprender estas interacciones es clave para desarrollar nuevos tratamientos para las infecciones virales que afectan a los órganos vitales.

Área de la Ciencia:

Ciencias Biomédicas
Inmunología
Patología

Sus antecedentes:

Las barreras de tejido sanguíneo (BTB) son interfaces críticas que protegen los órganos de los patógenos y regulan el transporte.
Los ejemplos incluyen la barrera hematoencefálica (BBB), la barrera hemato-retiniana (BRB) y la barrera hemato-testicular (BTB).
Los virus han desarrollado estrategias para superar estas barreras protectoras.

Objetivo del estudio:

Proporcionar una visión global de la arquitectura y la función de BTB.
Examinar los mecanismos por los que los virus interrumpen las BTB.
Resaltar las direcciones de investigación para mitigar la patogénesis viral y mejorar la eficacia del tratamiento.

Principales métodos:

Revisión de la literatura sobre las interacciones virales con las BTB.
Análisis de estrategias virales para violar y explotar las BTB.
Síntesis de la investigación actual sobre la disfunción de la barrera y las enfermedades virales.

Principales resultados:

Los virus comprometen las BTB, facilitando la entrada, la evasión inmune y la infección.
Los virus neurotrópicos interrumpen el BBB; los virus respiratorios dañan la barrera pulmonar; el virus Zika afecta al BTB.
Las rupturas de la barrera exacerban el daño tisular y complican el tratamiento.

Conclusiones:

Las BTB juegan un doble papel en la protección y la susceptibilidad durante las infecciones virales.
Elucidar las interacciones virus-BTB es crucial para comprender la patogénesis.
Las investigaciones adicionales pueden conducir a mejores terapias para las enfermedades virales asociadas a la barrera.

Immune Response Against Viral Pathogens

Immune Response Against Viral Pathogens

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...

Introduction to Virus

Introduction to Virus

Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Infection

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...
