Gene Regulation in Microbial Communities: Quorum Sensing01:28

Gene Regulation in Microbial Communities: Quorum Sensing

533
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Defense Against Bacterial Pathogens

2.6K
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...

Antimicrobial Proteins01:23

Antimicrobial Proteins

13.0K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

493
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

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.

Area of Science:

  • Periodontology
  • Immunology
  • Pharmacology

Background:

  • Periodontitis is a chronic inflammatory disease initiated by microbial dysbiosis.
  • Host inflammatory response significantly drives periodontitis progression.
  • Conventional antibiotic therapy targets microbial factors, but immunomodulatory effects are increasingly recognized.

Purpose of the Study:

  • To review the immunomodulatory mechanisms of antibiotics in periodontitis.
  • To explore how antibiotics influence host immune cells and inflammatory pathways.
  • To understand the impact on osteoimmunology in periodontal pathogenesis.

Main Methods:

  • Literature review of studies on antibiotic immunomodulatory effects.
  • Analysis of antibiotic influence on innate and acquired immunity.
  • Examination of effects on osteoimmunology and matrix metalloproteinases.

Main Results:

  • Antibiotics modulate innate immunity (e.g., PRRs, neutrophils, macrophages, epithelial barriers, cytokines).
  • Antibiotics affect acquired immunity, including T and B cell responses.
  • Key osteoimmunology components like RANKL/OPG pathway and MMPs are influenced.

Conclusions:

  • Antibiotics possess significant immunomodulatory properties beyond antimicrobial action.
  • Understanding these properties enhances therapeutic potential for periodontitis.
  • Potential for inflammation resolution, immune regulation, and tissue repair offers future research directions.
