Drosophila melanogaster adult flies have been extensively utilized as model organisms to investigate the molecular mechanisms underlying host antimicrobial innate immune responses and microbial infection strategies. To promote the D. melanogaster larva stage as an additional or alternative model system, a larval injection technique is described.

We present a protocol for direct vagus nerve injection in rats, enabling drug delivery directly into the nerve without post-injection complications. This method applies to preclinical neurological studies involving autonomic nervous system manipulation. It can be used for direct nerve injection for other nerves in rats and other species, with necessary modifications.

2026
Here, a protocol is presented to assess mouse meningeal lymphatic vessels (MLVs), which play an important role in multiple neurologic diseases. The goal of this protocol is to provide an integrated method that enables both functional evaluation of tracer drainage and detailed morphological characterization of the dorsal MLVs network.
FAQs
Killed mycobacterial components provide the immunostimulatory signal that activates innate immune pathways at the injection site. This signaling promotes local inflammation and helps antigen-presenting cells take up and present the associated antigen. The result is enhanced activation of antigen-specific immunity, supporting measurable antibody and T-cell responses in experimental immunology.
The mineral-oil emulsion provides the formulation context in which antigen and killed mycobacterial components are combined. This arrangement supports the local inflammatory environment needed for antigen uptake and presentation by antigen-presenting cells. Its significance is therefore biological as well as compositional: the formulation helps connect the injected antigen with innate activation and downstream antigen-specific immunity.
The formulation strengthens antigen-specific immune activation through innate inflammatory signaling, which supports both humoral and cellular responses. This dual outcome matters when a study needs to assess antibody production and T-cell activity rather than a single immune response. The response profile should therefore match the immunization question and the model’s intended immunological endpoint.
A high-level workflow begins by combining the antigen with CFA, administering the prepared formulation under an approved experimental plan, and monitoring animals for local and systemic inflammatory effects. The protocol should specify how immune responses will be evaluated and include welfare safeguards because CFA may cause substantial inflammation. These controls help distinguish intended immune activation from adverse responses.
Researchers apply CFA immunization in studies designed to generate robust antigen-specific responses, establish controlled models of inflammation or autoimmunity, and support infection research. The choice is driven by the experimental question: investigators may need enhanced antibody and T-cell responses, or an inflammatory context for examining disease-related immune mechanisms.
Within immunology and infection research, the protocol links innate sensing to adaptive antigen-specific responses. Mycobacterial components activate innate pathways, while antigen presentation by antigen-presenting cells helps support subsequent antibody and T-cell responses. This connection makes CFA useful for examining how inflammatory cues shape immunity in controlled immunization, inflammation, autoimmunity, and infection studies.
CFA can generate substantial local and systemic inflammatory effects, so welfare oversight is part of experimental design rather than an afterthought. Monitoring should address both the injection site and the animal’s overall condition, while protocol decisions should balance the need for a strong immune response against avoidable inflammatory burden. This is especially important in inflammation and autoimmunity models.
