Microorganisms in Medicine and Therapeutics

778
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.

Anatomy of the Intestines01:23

Anatomy of the Intestines

86.2K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Development of Immunocompetence01:22

Development of Immunocompetence

637
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.1K
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...

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

1.5K
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...

Area of Science:

  • Microbiology
  • Immunology
  • Developmental Biology

Background:

  • Human health depends on symbiotic interactions with the microbiome.
  • The early life period is characterized by rapid co-development of the host immune system and the microbiota.
  • Alterations in early life microbiota are linked to later-onset immune-mediated diseases.

Purpose of the Study:

  • To review data on early life microbial exposures and their association with immune-mediated diseases.
  • To highlight the critical window of immune system and microbiome co-development.
  • To identify opportunities for interventions promoting lifelong health.

Main Methods:

  • Review and synthesis of existing scientific literature.
  • Analysis of pre-, peri-, and early postnatal factors influencing newborn microbiota.
  • Extraction of overarching themes from the data.

Main Results:

  • Evidence suggests strong associations between early life microbiota modulators and immune-mediated diseases.
  • Minor alterations during early life co-development can have profound, long-lasting consequences.
  • The early life period represents a critical window of susceptibility for lifelong disease.

Conclusions:

  • Targeting the early life window of immune ontogeny and microbiome development offers significant potential for disease prevention.
  • Interventions like probiotic administration may be effective countermeasures.
  • Understanding this interaction is key to promoting lifelong health.
