Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

2.8K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

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.

Drugs for Peptic Ulcer Disease: Prostaglandin Analogs as Mucosal Protective Agents

1.5K
The gastric mucosa produces prostaglandins E2 (PGE2) and prostacyclin (PGI2), crucial in maintaining gastric health. They exert cytoprotective effects, including increasing bicarbonate secretion, releasing protective mucin, reducing gastric acid output, and preventing harmful vasoconstriction. These effects are mediated through various receptors, such as EP1, EP2, EP3, and EP4.
Non-steroidal anti-inflammatory drugs (NSAIDs) can induce peptic ulcers by inhibiting cyclooxygenase, decreasing...

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors01:24

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors

1.5K
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI)  tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.

Site-Targeted Drug Delivery Systems: Polymeric Carriers01:24

Site-Targeted Drug Delivery Systems: Polymeric Carriers

103
Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

1.8K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and...

  • Biomaterials Science
  • Computational Biology

Background:

  • Mucosal vaccination is a preferred route for preventing infections transmitted via mucosal surfaces, offering advantages like non-invasiveness and reduced disease transmission risk.
  • The limited availability of licensed mucosal vaccines is primarily attributed to the lack of safe and effective mucosal adjuvants.
  • Adjuvants are critical for enhancing vaccine-induced immunity and establishing immune memory.

Purpose of the Study:

  • To highlight the critical need for developing safe and effective mucosal adjuvants.
  • To advocate for a paradigm shift from empirical discovery to rational design in mucosal adjuvant research and development.
  • To emphasize the necessity of understanding the mechanisms underlying mucosal adjuvant activity.
