In the news

25-90% of individuals with primary immunodeficiencies will eventually develop complications.
Recurrent ear infections, sinusitis, pneumonia, and diarrhea are the most common symptoms in patients with Selective IgA Deficiency (SIgAD).
The prevalence of SIgAD is over 1 in 700, accounting for millions worldwide.
Common Variable Immune Deficiency (CVID)affects over
1 in 50,000 people and is classified as a rare disease.
What conditions are we focusing on?
What are maternal antibodies?
They are large proteins, derived from a mother’s breastmilk, that bind and neutralize pathogens.
Has this been done?
The novelty of our work is reflected in our granted US, Canadian and Japanese patents.
