Summary
Transcutaneous vaccination utilizes the skin's immune cells for effective delivery. Novel, pain-free methods enhance transdermal vaccination and immunotherapy for all ages.
Area of Science:
- Immunology
- Dermatology
- Vaccinology
Context:
- The skin's immune cells in the epidermis and dermis are increasingly recognized as key targets.
- Historically, skin vaccination (e.g., Jenner's cowpox) was rudimentary, but recent research highlights its immunological potential.
- The skin acts as a barrier to topical administration of large molecules like vaccines and immunotherapies.
Purpose:
- To explore the immunological properties of the skin for vaccination and immunotherapy.
- To review novel methods for overcoming the skin's barrier function for transcutaneous delivery.
- To highlight the potential of non-invasive, transcutaneous approaches for both children and adults.
Summary:
- Recent discoveries over the last 20 years have revealed the significant immunological properties of the skin.
- Immunological cells residing in the epidermis and dermis are viable targets for transcutaneous vaccination and immunotherapy.
- Various chemical, biochemical, and physical methods have been developed to facilitate the transcutaneous delivery of therapeutic agents, overcoming the skin's natural barrier.
- Many of these novel methods are pain-free, making them particularly suitable for pediatric populations.
- Non-invasive transcutaneous vaccination and immunotherapy also offer convenience for adult self-administration.
- Clinical trials for future products utilizing these approaches are showing promising results.
Impact:
- Advances in transcutaneous vaccination and immunotherapy offer potential for more accessible and patient-friendly delivery methods.
- Pain-free and self-administrable options could improve vaccination compliance and therapeutic outcomes.
- The findings support the development of next-generation vaccines and immunotherapies leveraging the skin's immune potential.
- Non-invasive delivery systems may revolutionize the administration of biologics and vaccines, particularly for vulnerable populations.

2.5K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

01:18Transdermal Drug Delivery Systems
213
Transdermal drug delivery systems (TDDS) enable the controlled release of drugs across the skin into systemic circulation. They are particularly advantageous for drugs with short half-lives or narrow therapeutic indices, as they maintain consistent plasma concentrations and reduce the risk of subtherapeutic or toxic levels.TDDS are categorized into monolithic, reservoir, and mixed systems. Monolithic systems embed the drug in a polymer matrix, where diffusion governs release. Reservoir systems...

01:29Drug Delivery: Parenteral Route
2.8K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

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.

3.6K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
