Special Issue Information

Dear Colleagues,

Immune systems protect animals from threats by parasites, bacteria, and viruses. Most of what we know today about the composition, function, and regulation of the two fundamental branches of the immune system—innate immunity and adaptive immunity—comes from studies on mammals. However, recently, there has been an increased interest in fish immunology for several reasons. The innate system also plays an instructive role in the acquired immune response and homeostasis and is therefore equally important in higher vertebrates. The innate immune system is a fundamental defense mechanism of fish. Innate immunity provides some form of defense against pathogens in all multicellular organisms both cartilaginous and bony fish. The innate immune system is divided into physical barriers, cellular and humoral components. Humoral parameters include growth inhibitors, several lytic enzymes and components of the complement pathways, agglutinins and precipitins (opsonins, primarily lectins), natural antibodies, cytokines, chemokines and antibacterial peptides. Several external and internal factors can influence the activity of innate immune parameters. Temperature changes, handling and crowding stress can have suppressive effects on innate parameters, whereas several food additives and immunostimulants can enhance different innate factors. Additionally, estrogen can modulate several functions of immune system in teleosts fish via ER-mediated pathways. Knowledge of mechanisms is important for the use and design of vaccines, now so essential for expanding aquaculture industry, whereas studies of fish immunology contribute to the understanding of the evolution of adaptive immunity.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fishes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The interaction between the immune and endocrine systems has long been recognized in vertebrates. In fish, it is known that the prevalence and intensity of such infections are higher in males than in females and probably related to sex steroid hormone levels. In addition, the immune response in the fish gonad tissues is specifically regulated to prevent infertility. This condition is used by some pathogens to colonize the fish gonad, evade the systemic immune response, and so spread to the progeny. This review brings up to date our knowledge concerning fish gonad immunity and its regulation, immune-endocrine interactions, and how some pathogens use this tissue to spread to the progeny through vertical transmission. More specifically, we will look at the case of the European sea bass and nodavirus (NNV). Sea bass is a very susceptible fish species to NNV infections, and this virus has been associated to vertical transmission since it is detected in gonad fluids as well as in testicular gametes. In fact, sea bass immunity in the gonad is regulated in a very different way to other target tissues (brain and retina) or immune-relevant tissues (head-kidney or spleen). Full article
