Acufection-Mediated Delivery of Immune-Related Genes into Mouse Skin Tissues

The video demonstrates a method for directly transferring the interleukin-15 encoding plasmid DNA into the skin tissue of an interleukin-15 deficient mouse model through acupuncture using microneedles. These microneedles generate micropunctures in the outermost skin layer, facilitating the absorption and transfection of plasmid DNA into the epidermal cells, including keratinocytes, within the skin tissue.

This video demonstrates a technique to generate a murine model of skin wound infection. Upon infecting mice — engineered to express a fluorescent protein in neutrophils — with a genetically modified bioluminescent Staphylococcus aureus — a pathogenic bacteria. The bacterial burden at the infection site and the neutrophil recruitment dynamics can be studied using whole animal imaging.

This protocol describes the induction of an ischemia-reperfusion (IR) model on mouse ear skin using magnet clamping. Using a custom-built intravital imaging model, we study in vivo inflammatory responses post-reperfusion. The rationale behind the development of this technique is to extend the understanding of how leukocytes respond to skin IR injury.

This video demonstrates an in vivo technique to assess a test antigen by inducing skin inflammation in a murine model. The test antigen—a hapten in an oil/acetone solution—is topically applied to the skin of the mouse ear, and inflammation of the skin is assessed after an adequate period.

What is the Immune System?

Overview The immune system comprises diverse biological structures and processes that protect the body from disease. These processes can be classified into innate and adaptive immunity. To work effectively, the immune system needs to detect pathogens by distinguishing the body’s own structures from foreign elements. If this determination fails, autoimmune diseases occur in which the immune system reacts against the body’s own tissue. The Innate Immune System Acts Fast and Non-specifically
FAQs
Keratinocytes do more than form a physical boundary: they produce antimicrobial peptides and inflammatory signals that can act when microbes threaten tissue. These outputs connect barrier integrity with immune detection and help shape whether the response remains protective or becomes inflammatory. In infection research, keratinocyte activity provides an important indicator of early skin defense.
Langerhans cells detect threats in the skin and help initiate adaptive immune responses, extending protection beyond immediate innate defenses. Their position within the epidermal environment allows researchers to examine how local threat detection becomes broader immune activation. This makes them especially relevant when studying communication between early host defense and longer-term immune responses.
Resident microbes contribute to tissue balance alongside physical barriers, immune cells, and signaling molecules. Their presence places skin immunity in a context broader than direct pathogen elimination, because protective activity must coexist with normal tissue conditions. Studying this relationship helps clarify how host defenses operate without disrupting the balance required for healthy skin.
Insufficient immune activity can weaken protection against infection, whereas excessive activity can contribute to inflammatory skin disease. The outcome depends on how barriers, immune cells, signaling molecules, and resident microbes interact. This regulatory perspective helps explain why research addresses both stronger defense and control of inflammation rather than treating immune activation as uniformly beneficial.
Skin immunity provides a model for examining host-pathogen interactions, which describe how infectious organisms and host defenses affect one another. It also supports research on wound healing and inflammatory skin disease. By considering barriers, immune responses, and tissue balance together, investigators can relate local skin events to broader questions about infection and immune regulation.
Findings from skin immunity research can inform strategies for preventing infections, improving vaccines, and repairing damaged barriers. They can also guide treatments for conditions linked to excessive or insufficient immune activity. The value of this work comes from connecting specific skin defenses and regulatory processes with practical outcomes in prevention, tissue recovery, and disease management.
