Studying the immune system of Chinese giant salamander contributes to understanding the evolution of immune systems of vertebrates. The NLR-related protein 3 (NLRP3) inflammasome comprised of NLRP3, ASC and caspase-1 play important roles in the host innate immunity. However, little is know about the NLRP3 inflammasome components in Chinese giant salamander. In this study, the NLRP3, apoptosis-associated speck-like protein (ASC) and caspase-1 (adaNLRP3, adaASC and adaCaspase-1) were characterized from Chinese giant salamander. The proteins of these three genes shared similar motifs and structures with their mammalian counterparts, with a PYD motif, a nucleotide-binding domain (NACHT) motif, and four leucine-rich repeat domain (LRR) motifs identified in adaNLRP3, a pyrin domain (PYD) motif and a caspase recruitment domain (CARD) motif in adaASC, and a CARD motif and a CASc motif in adaCaspase-1. These three genes were constitutively expressed in the skin, heart, lung, kidney, muscle, brain, spleen, and liver of Chinese giant salamander. Following <em>Aeromonas hydrophia</em> infection, all the three genes were up-regulated in various tissues. Molecular docking analysis revealed that the key residues involved in forming the adaNLRP3/adaASC complex were located in the PYD motifs, and that involved in forming the adaASC/adaCaspase-1 complex were located in the CARD motifs. Further analysis revealed that the hydrogen bonds and salt bridges had crucial roles in the formation of adaNLRP3/acaASC and adaASC/adaCaspase-1 complexes. To the best of our knowledge, this is the first report on the NLRP3 inflammasome components in Chinese giant salamander which will be helpful in further understanding the function of the NLRP3 inflammasome and in elucidating its role in the immune response to microbes.</p></div>","PeriodicalId":11228,"journal":{"name":"Developmental and comparative immunology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the first chemokines identified, CXCL8 functions as a key neutrophil activator, recruiting neutrophils to sites of inflammation. Several viral infections, including zoonotic coronaviruses and poxviruses, have been reported to induce the expression of CXCL8. Dromedary camels are known to harbor several potentially zoonotic pathogens, but critical immune molecules such as chemokines remain unidentified. We report here the identification of CXCL8 from the dromedary camel - the first chemokine identified from camelids. The complete dromedary CXCL8 cDNA sequence as well as the corresponding gene sequence from dromedary and two New World camelids - alpaca and llama were cloned. CXCL8 mRNA expression was relatively higher in PBMC, spleen, lung, intestine, and liver. Poly(I:C) and lipopolysaccharide stimulated CXCL8 expression <em>in vitro</em>, while interferon treatment inhibited it. <em>In vitro</em> infection with potentially zoonotic camelpox virus induced the expression of CXCL8 in camel kidney cells. Toxicological studies on camelids have been limited, and no biomarkers have been identified. Hence, we also evaluated CXCL8 mRNA expression as a potential biomarker to assess heavy metal toxicity in camel kidney cells <em>in vitro</em>. CXCL8 expression was increased after <em>in vitro</em> exposure to heavy metal compounds of cobalt and cadmium, suggesting potential utility as a biomarker for renal toxicity in camels. The results of our study demonstrate that camel CXCL8 plays a significant role in immunomodulatory and induced toxicity responses in dromedary camels.</p></div>","PeriodicalId":11228,"journal":{"name":"Developmental and comparative immunology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142145374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breeding sheep for gastrointestinal nematode resistance is a sustainable alternative to reduce dependence of anthelmintic drugs, and differences in the degree of resistance between breeds have been reported. Here we compare two sheep breeds (Santa Ines and Ile de France), concerning the differences in innate and adaptive immune response involved in the resistance against <em>H. contortus</em> infection. Immunohistochemical analyses of the abomasum were conducted in naïve Santa Ines (n = 14) and Ile de France (n = 12) lambs randomized into four groups: infected Santa Ines (n = 8), non-infected control Santa Ines (n = 6), infected Ile de France (n = 8), and non-infected control Ile de France (n = 4). The infected lambs were initially infected with <em>H. contortus</em> infective larvae at 14 days of age, and multiple infections were conducted every second day until they reached 66 days of age. There was a significant effect (P &lt; 0.001) of the infection with increase in numbers of CD3⁺ T; CD79α+ B; GATA3+ Th2/ILC2; POU2F3+ tuft cells; FOXP3+ T reg; and IgE + cells in the fundus of the abomasal mucosa in both Santa Ines and Ile de France lambs. Nevertheless, the infected Santa Ines lambs presented the highest averages for CD79α+ B; GATA3+ Th2/ILC; IgE + cells; and POU2F3+ tuft cells and there was a significant association of the breed and infection status with regards to POU2F3+ tuft cells, with the highest mean in the infected Santa Ines group. The infected Santa Ines group had three lambs with high degree of resistance and five lambs that showed a moderate infection.

This study investigates the role of Tripartite Motif (TRIM) family in the innate immune response of grass carp, focusing on TRIM103 from <em>Ctenopharyngodon Idella</em> (<em>Ci</em>TRIM103), a member of the TRIM-B30.2 family, which includes proteins with the B30.2 domain at the N-terminus, known for antiviral properties in teleosts. <em>Ci</em>TRIM103 bind to the outer coat proteins VP5 and VP7 of GCRV.

Demonstrations using overexpression and RNA interference (RNAi) techniques have shown that <em>Ci</em>TRIM103 effectively inhibits GCRV replication. Moreover, molecular docking and pulldown assays suggest potential binding interactions of <em>Ci</em>TRIM103's B30.2 domain with GCRV outer coat proteins VP5 and VP7.
