Microorganisms in Medicine and Therapeutics

1.2K
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.

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

10.0K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Defense Against Bacterial Pathogens

3.1K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

14.1K
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...

Introduction to Innate and Adaptive Immunity01:21

Introduction to Innate and Adaptive Immunity

10.4K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Area of Science:

  • Immunology
  • Microbiology
  • Gastroenterology

Background:

  • Mucosal surfaces host diverse microbes essential for immune system regulation.
  • The host employs intrinsic and innate mechanisms to maintain a barrier between microbiota and host.
  • Microbiota can induce robust adaptive immune responses, including antibody production.

Purpose of the Study:

  • To review the interplay between the microbiota and the adaptive immune system.
  • To focus on the induction of mucosal and systemic antibody responses.
  • To highlight the role of maternal antibodies and microbial antigen-specificity in T-cells.

Main Methods:

  • Literature review of recent studies on microbiota-immune system interactions.
  • Analysis of mechanisms inducing adaptive immunity at mucosal sites.
  • Examination of T-cell responses to microbial antigens.

Main Results:

  • Microbiota plays a critical role in stimulating and regulating adaptive immunity.
  • Both mucosal and systemic antibody responses are influenced by the microbiota.
  • Maternal antibodies and microbial antigen-specific T-cells have newly defined roles.

Conclusions:

  • The microbiota is integral to adaptive immune system development and function.
  • Understanding microbiota-immune interactions is key for immune health.
  • Further research is needed to fully elucidate microbial antigen-specific T-cell responses.
