Insights

MicroRNAs (miRNAs) regulate gene expression and are implicated in inflammatory diseases. This review explores "inflammamiRs" as potential therapeutics, addressing challenges in their development and clinical application.

Area of Science:

  • Molecular Biology
  • Genetics
  • Immunology

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
  • Dysregulated miRNA expression is observed in various diseases, including inflammatory and autoimmune conditions, with specific miRNAs termed "inflammamiRs."
  • The precise methods, therapeutic approaches, and biological materials used are critical when studying miRNAs.

Purpose of the Study:

  • To review the role of specific inflammamiRs in inflammatory diseases.
  • To discuss the challenges associated with miRNA-based therapeutics, such as off-target effects and delivery.
  • To provide insights into developing safe and targeted miRNA therapies and their clinical trial status.

Main Methods:

  • Literature review of studies on microRNAs and inflammatory diseases.
  • Analysis of the therapeutic potential and challenges of "inflammamiRs."
  • Discussion of miRNA delivery methods and clinical trial data.

Main Results:

  • MicroRNAs play a significant role in regulating inflammatory pathways.
  • Identifying potent therapeutic miRNA candidates is challenging due to factors like off-target effects.
  • Effective and targeted delivery remains a key hurdle for miRNA-based therapies.

Conclusions:

  • InflammamiRs show promise as therapeutic agents for inflammatory diseases.
  • Overcoming challenges in specificity, dosage, and delivery is crucial for successful miRNA therapy.
  • Further research and clinical trials are needed to establish the full potential of inflammamiRs in medicine.

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Drug Delivery: Overview01:16

Drug Delivery: Overview

The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Additional Routes of Drug Administration

Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

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

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...
