Immunsystem I.M.S.

Immunsystem I.M.S. is a private Swedish biotechnology and diagnostics company based in Uppsala focused on avian IgY antibodies for both diagnostic and therapeutic use. The company was founded by researchers associated with Uppsala University and the Swedish University of Agricultural Sciences and has historically specialized in antibody production, purified antibodies, and diagnostic kits. Its best-documented therapeutic program is an avian polyclonal IgY antibody directed against Pseudomonas aeruginosa that received EU orphan designation for cystic fibrosis. Available public information suggests the company remains small and private, with limited recent disclosure on clinical development progress or a broader modern pipeline. Overall, the company appears to combine antibody know-how in diagnostics with niche therapeutic development based on low-toxicity IgY products.
