Summary
Topical antigen application on the skin targets Langerhans cells (LCs), acting as sentinels. This needle-free vaccination route effectively induces humoral and cellular immune responses, showing significant clinical promise.
Area of Science:
- Immunology
- Dermatology
- Vaccinology
Context:
- The skin is an immunologically active organ.
- Langerhans cells (LCs) are specialized immune cells in the epidermis.
- LCs function as sentinels, initiating immune responses.
Purpose:
- To explore the potential of topical antigen application for vaccination.
- To investigate the induction of immune responses via the skin.
- To evaluate Langerhans cells as targets for novel vaccination strategies.
Summary:
- Topical application of antigens to the skin effectively targets Langerhans cells (LCs).
- This method induces both humoral and cellular immune responses.
- The study highlights the potential of skin-based, needle-free vaccination.
Impact:
- Novel needle-free vaccination strategies.
- Enhanced delivery of vaccines via the skin.
- Potential for improved vaccine efficacy and patient compliance.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

Overview
Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
