Preparing an Antigen-Adjuvant Emulsion to Induce Autoimmune Encephalomyelitis

2025
This video demonstrates an efficient homogenization technique to generate an antigen-adjuvant emulsion to induce experimental autoimmune encephalomyelitis (EAE) in a murine model. The emulsion contains an autoantigen — myelin oligodendrocyte glycoprotein (MOG) — in the water phase, surrounded by a continuous oil phase comprising an inactivated pathogenic bacteria. The emulsion ensures a sustained release of antigens for a prolonged immune response.

To induce experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, mice are immunized with a water-in-oil emulsion containing an autoantigen and complete Freund's adjuvant. While several protocols exist for the preparation of these emulsions, a rapid, simple, and standardized homogenization protocol for emulsion preparation is presented here.

This video demonstrates the induction of systemic inflammation in an anesthetized mouse. The injection of mycobacterial antigen-adjuvant depots triggers cytokine release and localized inflammation. Lymphatic vessels open, enabling immune cell entry into lymph nodes and activation of T cells, which release pro-inflammatory cytokines, leading to widespread inflammation.

FAQs
Microscopic droplets affect how the antigen is delivered and how strongly the surrounding tissue responds to the formulation. Their organization within the mixed phases can promote local innate immune activation and support recruitment of antigen-presenting cells. These early events help determine how efficiently antigen is processed and how effectively subsequent adaptive antibody and T-cell responses develop.
Antigen-presenting cells connect local innate activation with adaptive immunity. After recruitment, they process the delivered antigen and stimulate immune cells that generate antibody and T-cell responses. This cellular pathway explains why an antigen-adjuvant emulsion can do more than deliver antigen alone: it helps create the conditions needed for a coordinated and potentially more durable protective response.
Properties of the emulsion, including the behavior of its microscopic droplets and the organization of its oil and aqueous phases, can influence antigen delivery and local immune activation. These differences may alter antigen-presenting-cell recruitment and activation, with consequences for antibody production, T-cell responses, and vaccine durability. Formulation design therefore becomes an important variable in immunological studies.
Researchers can assess whether a formulation strengthens antibody production, T-cell responses, and the durability of vaccine-induced immunity. These outcomes provide complementary information: antibodies reflect one major protective response, T cells indicate another arm of adaptive immunity, and durability shows how well the response persists. Together, they help compare formulation performance rather than focusing only on immediate immune activation.
In infection research, the formulation serves as a way to examine how vaccine design affects protective immunity against infectious diseases. Investigators can vary or compare formulation properties and then evaluate resulting antibody, T-cell, and durability outcomes. This approach supports the broader goal of identifying immunization strategies that improve vaccine potency while guiding the development of safer and more effective vaccines.
Results from antigen-adjuvant emulsion studies can reveal links between formulation properties, antigen delivery, innate activation, and adaptive immune outcomes. That information helps researchers identify designs that produce stronger or longer-lasting protection without treating potency as the only criterion. In immunology and infection research, these findings contribute to rational strategies for improving vaccine effectiveness and informing safer immunization approaches.
