Enteric viral antigens and other luminal pro-inflammatory non-bacterial antigens

Enteric viral antigens and other luminal pro-inflammatory non-bacterial antigens represent a broad class of substances within the gastrointestinal tract that can trigger pathological immune responses (Wilson et al., 2013). This category includes viral particles (such as rotavirus or norovirus), fungal components, and dietary proteins that act as pro-inflammatory stimuli when the intestinal barrier is compromised (Petschow et al., 2014). In diseases such as Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD), these antigens penetrate the mucosal layer, leading to chronic immune activation and further barrier breakdown (Good et al., 2015). Therapeutic agents like serum-derived bovine immunoglobulin/protein isolate (SBI) are designed to bind these antigens within the lumen, effectively neutralizing them and preventing their interaction with the host's immune cells (Wilson et al., 2013). By sequestering these triggers, such therapies aim to reduce intestinal inflammation and restore normal gut function and permeability (Petschow et al., 2014). This approach is particularly relevant in conditions characterized by 'leaky gut' where the translocation of these antigens is a primary driver of symptoms (Good et al., 2015).
