Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

570
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines01:23

Anatomy of the Intestines

72.9K
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...

Physiology of Enteric Nervous System and Gut Health

383
The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

Mitochondria01:37

Mitochondria

14.2K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

2.3K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

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:

  • Microbiology
  • Gerontology
  • Human Physiology

Background:

  • The human gut microbiota consists of trillions of microorganisms crucial for host health.
  • These microbes produce metabolites vital for bodily functions and exhibit a bidirectional relationship with the host.
  • Microbiota health is influenced by lifestyle, diet, and social factors, and impacts health outcomes in an age- and sex-dependent manner.

Purpose of the Study:

  • To review the scientific evidence supporting the bidirectional relationship between the gut microbiota and biological aging.
  • To explore how gut microbiota composition affects organ function and the aging process.

Main Methods:

  • Literature review of existing studies on gut microbiota and aging.
  • Analysis of research linking gut microbiota disruption to chronic diseases and accelerated aging.
  • Examination of the role of microbial metabolites in host health and aging.

Main Results:

  • Gut microbiota disruption and reduced diversity are associated with negative health outcomes, including neurodegenerative diseases.
  • Impaired gut microbiota composition accelerates organ decline and biological aging.
  • The gut microbiota plays a significant role in modulating the aging process.
