Insights

Even with suppressed virus, HIV infection causes immune activation. Microbial products translocating from the gut are key drivers, and new therapies target this process.

Area of Science:

  • Immunology
  • Microbiology
  • Virology

Background:

  • HIV infection leads to persistent systemic immune activation, even when viral load is suppressed by antiretroviral therapy (ART).
  • Intestinal damage is a significant consequence of HIV infection.
  • Microbial products translocating from the gut are increasingly recognized as contributors to immune activation in HIV.

Purpose of the Study:

  • To review the mechanisms linking intestinal damage, microbial translocation, and immune activation in HIV infection.
  • To discuss emerging therapeutic strategies targeting microbial translocation in HIV.

Main Methods:

  • Review of existing literature on HIV, intestinal integrity, microbial translocation, and immune activation.
  • Analysis of pathways involved in microbial product-mediated immune stimulation.
  • Discussion of novel therapeutic interventions.

Main Results:

  • HIV infection causes intestinal damage, facilitating the translocation of microbial products into the bloodstream.
  • These microbial products activate immune cells through specific molecular pathways.
  • Therapies aimed at reducing microbial translocation show promise in mitigating immune activation.

Conclusions:

  • Microbial translocation is a critical factor driving persistent immune activation in HIV-infected individuals on ART.
  • Targeting microbial translocation represents a promising therapeutic avenue to improve immune function and clinical outcomes in HIV.
  • Further research into gut health and microbial translocation is essential for comprehensive HIV management.

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...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

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 disorders...
Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
