Elucidating the mechanisms of estrogens-induced immunomodulation in teleost fish is of great importance due to the observed worldwide continuing decrease in pristine environments. However, little is know about the immunotoxicological consequences of exposure to these chemicals in fish, or of the mechanisms through which these effects are mediated. In this review, we summarize the results showing estrogens (natural or synthetic) acting through estrogen receptors and regulating specific target genes, also through microRNAs (miRNAs), leading to modulation of the immune functioning. The identification and characterization of miRNAs will provide new opportunities for functional genome research on teleost immune system and can also be useful when screening for novel molecule biomarkers for environmental pollution.

plecoglossicida infection induces neutrophil autophagy-driven NETosis in large yellow croaker .

Neutrophil extracellular traps (NETs) are crucial for the immune defense of many organisms, serving as a potent mechanism for neutrophils to capture and eliminate extracellular pathogens. While NETosis and its antimicrobial mechanisms have been well studied in mammals, research on NETs formation in teleost fish remains limited. In this study, we used the large yellow croaker () as the study model to investigate NETosis and its role in pathogen defense.

Maximizing the life-long reproductive output would lead to the prediction that short-lived and fast aging species would undergo no - if any - reproductive senescence. Turquoise killifish (Nothobranchius furzeri) are naturally short-lived teleosts, and undergo extensive somatic aging, characterized by molecular, cellular, and organ dysfunction following the onset of sexual maturation. Here, we tested whether naturally short-lived and fast aging male turquoise killifish maximize reproduction and display minimal - if any, reproductive senescence.

Immunological memory in a teleost fish: common carp IgM B cells differentiate into memory and plasma cells.

Front Immunol

From ancient cold-blooded fishes to mammals, all vertebrates are protected by adaptive immunity, and retain immunological memory. Although immunologists can demonstrate these phenomena in all fish, the responding cells remain elusive, without the tools to study them nor markers to define them. Fundamentally, we posited that it is longevity that defines a memory cell, like how it is antibody production that defines a plasma cell.

Palmitoylation-mediated NLRP3 inflammasome activation in teleosts highlights evolutionary divergence in immune regulation.

NLRP3 inflammasome activation is pivotal for cytokine secretion and pyroptosis in response to diverse stimuli, playing a crucial role in innate immunity. While extensively studied in mammals, the regulatory mechanisms governing NLRP3 activation in non-mammalian vertebrates remain largely unexplored. Teleosts, as basal vertebrates, represent an ideal model for exploring the evolutionary trajectory of inflammasome regulation.

Fas-associated protein with Death Domain (FADD) is a crucial signaling component of apoptosis and a vital immunomodulator on inflammatory signaling pathways. However, information on FADD-mediated apoptosis and immune regulation is limited in teleost. We herein cloned a FADD homolog, AjFADD, from Japanese eel (Anguilla japonica).
