Expert Opinion on Drug Delivery
|February 14, 2014
Summary
Microneedle patches offer a painless alternative to traditional vaccines, potentially improving immune responses and stability for global distribution. This novel skin delivery method shows promise for influenza vaccines and future pandemic preparedness.
Area of Science:
- Immunology
- Vaccinology
- Dermatology
Background:
- Traditional vaccines use hypodermic needles, causing fear and disposal issues.
- Skin delivery offers a painless alternative, potentially reducing vaccine dosage.
- Microneedles are a novel approach for painless skin delivery of vaccines.
Purpose of the Study:
- Review skin vaccination approaches and devices.
- Focus on microneedle-based influenza vaccine delivery.
- Discuss immune response to microneedle vaccination.
Main Methods:
- Review of existing literature on skin vaccination.
- Analysis of studies using microneedles for influenza vaccines.
- Evaluation of immune responses elicited by microneedle delivery.
Main Results:
- Microneedle vaccination is painless and elicits stronger immune responses in preclinical studies.
- Potential for improved vaccine responses in high-risk populations.
- Dry vaccine formulations enhance stability for global distribution.
Conclusions:
- Cutaneous influenza vaccine delivery via microneedles is advantageous.
- Painless administration and enhanced immune responses are key benefits.
- Improved vaccine stability facilitates rapid global distribution for outbreaks.

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the...

01:29Immune Response Against Viral Pathogens
2.4K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

11.1K
A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.
