Mucus is the slippery secretion produced by mucus cells (i.e. goblet cells) among the epithelial lining of the intestine. Mucus serves to protect and lubricate the bowel.
M cells (microfold cells) are specialized cells found in the epithelium covering a Peyer’s patch. The function of an M cell is to sample the antigen directly from the lumen and deliver it to antigen-presenting cells, such as dendritic cells, and lymphocytes.
Peyer’s patches are regions of lymphoid tissue found in the wall of the small intestine. Peyer’s patches function as immune sensors of the intestine and facilitate the generation of the immune response within the mucosa.
Goblet cells are specialized cells which reside throughout the length of the small and large intestine and are responsible for the production of protective mucus.

Cytokines are small proteins or glycoproteins that help the immune system to mount and coordinate an effective immune response by aiding cell to cell communication.
Helper T cells are a subset of T cells that play a major role in controlling and regulating the adaptive immune response by ‘helping’ to activate other white blood cells to perform their respective functions. Helper T cells usually express the CD4 co-receptor.
Beta glucans are a class of polysaccharides found widespread in nature and may be derived from a variety of sources. Many beta glucans derived from fungi have the ability to behave as immunomodulators. In this illustration beta glucan is activating a macrophage, triggering a cascade of immune events to occur.
IgM is an immunoglobulin found in colostrum which serves as a first line of defense, attacking bacteria and rendering them inactive.
IgA is an immunoglobulin found in colostrum which serves as a first line of defense, protects mucosal surfaces and prevents the attachment of pathogens to the them.

Salmonella are rod-shaped, gram-negative bacteria that can adhere to the intestinal tract resulting in severe diarrhea and potentially life-threatening dehydration and electrolyte imbalance.
Villi (singular: villus)
are small, finger-like projections that protrude from the epithelial lining of the intestinal wall. Villi increase the internal surface area of the intestinal wall allowing for greater absorption.

Probiotics are beneficial bacteria that can colonize the intestinal tract. Probiotics compete with the “bad” bacterial inhabitants for space along the intestinal wall.
Colostrum is the first milk produced by lactating cows. Colostrum contains a potent array of immune factors which work synergistically with one another to reduce inflammation and to provide broad spectrum defense against pathogens such as bacteria, fungi, protozoa and viruses. Colostrum also contains several growth factors which act to repair damage to the gut lining and restore gut integrity. Colostrum has even been shown to increase the surface area of the intestinal lining, thereby improving nutrient absorption.
