IntroductionAquaculture is the most dynamic and rapidly expanding food production sector. Fish and shellfish have been thoroughly studied in terms of immunostimulants, both at the cellular and hole level. It has been employed as a preventative measure to reduce animal illnesses and diseases, as well as alarm molecules that stimulate the immune system. Modern aquaculture is growing to be more sig..

Lymph nodes are criticalsites for immune cells to connect, exchange information, and initiate responses to foreign invaders. More than 90% of the cells in each lymph node—the T and B lymphocytes of the adaptive immune system—only reside there temporarily and are constantly moving around as they search for foreign substances (antigen). When there is no infection, T and B cells migrate within dist..

1. The Interferon family Interferons (IFN) were first discovered by Isaacs and Lindemann in 1957. The initial experiments were performed in chick chorioallantoic membranes in a nutrient fluid where the addition of influenza virus stimulated the production of a protein which interfered or prevented viral replication. In 1965, IFNγ was discovered as a viral inhibitory protein produced by lymphocyt..

IntroductionImmune enhancers are substances that are unrelated to antigens and can augment the body´s immune response when used alone or simultaneously with antigens, whereas immune adjuvants are substances that can be used in combination with vaccines to improve the immune response to vaccine antigens [1]. Studies have shown that several substances exist with immuneenhancing effects, such as oi..

INTRODUCTION Sustainable food supply to feed the demand of the projected world population by 2050 is a challenge, in which aquaculture is predicted to be the main source of aquatic dietary proteins. Such growth will unavoidably involve the implementation of innovative aquaculture production strategies, targeting issues related to effective health management and animal welfare (1). In this regard..

1. IntroductionFish are continuously exposed to a microbial-rich environment (freshwater or seawater) that circulates through and reaches every epithelial barrier of their body. Thus, compared to terrestrial animals, aquatic animals have a greater challenge coping with high microbial loads, which bombard their mucosal epithelial barriers. The main mucosa-associated lymphoid tissues (MALT) of tel..

INTRODUCTIONInterferons (IFNs) are pleiotropic cytokines with antiviral, antitumor and immunomodulatory properties, being central coordinators of the immune response (1). The term “interferons” comes from the description of molecules protecting cells by “interfering” with viral infection (2, 3). Three major types of IFNs are distinguished by their sequence identity, genetic loci, cell of origin,..
