In the primary humoral immune response, a single class IgM in monomeric form is initially secreted. The secondary response induced by a subsequent exposure to the same antigen will be mainly characterized by the production of IgG isotype but at higher titre and affinity.

Specific humoral immunity is mediated by glycoproteins called antibodies or immunoglobulins.

The main mechanism of defense against intracellular infections, particularly virus.

The role of each player in the innate immunity response: Type 1 Interferons and pro-inflammatory cytokines, complement, acute phase proteins, antimicrobial proteins, phagocytes, NK cells, γ/δ T lymphocytes,...

Recognition of the pathogen is the first step of defensive immune response; both innate and specific immunity have mechanism to recognize the pathogen.

What the cytokines are, what they do and how they work on the immune system.

This article reviews major immune cells: Neutrophils, macrophages, natural killer, lymphocytes, dendritic cells, mast cells...

This article summarizes the primary (thymus and bone marrow) and secondary (lymph nodes, spleen, MALT, tonsils, and skin immune system) lymphoid organs in pig.

Biological alterations in immune and intestinal systems occur immediately after weaning that affect subsequent pig growth and health.

This article introduces us to the complex world of porcine immunology.

The rate and sequence of mucosal immune maturity from birth to an ‘adult-type’ pig is an important determinant of subsequent performance, health and survival, and hence impacts on the efficiency and profitability of pork production.

Cross-sectional sampling (different age groups during one herd visit) has the advantage that results are obtained quickly.

The interaction between M. hyopneumoniae and its host make M. hyopneumoniae one of the most important contributors to porcine respiratory disease.

One issue is to overcome maternal immunity, which is true for all PCV2 vaccines in the market, and another is whether the most from these vaccines is achieved independently of the PCV2 antibody titre at vaccination

Tryptophan has positive effects on voluntary feed intake. This greater feed intake leads to increased growth performance and improved feed conversion ratio in piglets, and to lower body weight losses in sows during lactation.
