Summary
Human hair follicles act as key entry points for topical compounds, influencing drug delivery. Targeting these follicles offers new strategies for skin disease treatment and therapies.
Area of Science:
- Dermatology
- Pharmacology
- Biomedical Engineering
Background:
- Topical compound penetration varies across human skin regions.
- Hair follicles increase surface area and disrupt the epidermal barrier, facilitating compound entry.
- Hair follicles serve as reservoirs and major entry points for topical applications.
Purpose of the Study:
- To investigate the role of hair follicles in topical compound delivery.
- To explore strategies for targeting specific skin compartments via hair follicles.
- To enable precise delivery of active compounds for therapeutic benefits.
Main Methods:
- Review of existing literature on topical drug delivery and follicular penetration.
- Analysis of the structural contribution of hair follicles to compound absorption.
- Exploration of current and emerging drug carrier and delivery systems.
Main Results:
- Hair follicles significantly influence the penetration of topically applied compounds.
- Follicular targeting allows for localized delivery, potentially reducing systemic side effects.
- The hair follicle is a critical target for advanced topical therapies.
Conclusions:
- Targeting hair follicles is a promising strategy for enhanced topical drug delivery.
- Follicular delivery systems can lead to novel treatments for skin and hair follicle-associated diseases.
- This approach holds potential for advancements in gene therapy and immunotherapy.

02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
