As reported here, RNA-sequencing was used to initiate the characterization of the signaling pathways involved in eliciting the development of CD8 CTL, starting with the characterization of the activation status of genes in monocyte-derived macrophages (MoMΦ) following uptake and processing MMP for the presentation of antigenic epitopes to CD4 and CD8 T cells. Activation status was compared with the uptake and processing of LPS, a nonspecific stimulator of macrophages. 1609 genes were identified that were upregulated, and 1277 were downregulated three hours after uptake and processing MMP. No significant difference was observed in the cytokine genes selected for analysis of the signaling that must occur between APC, CD4, and CD8 for the development of CTL. The initial observations indicate screening of the transcriptome should include genes involved in signaling between APC and CD4, and CD8 regardless of their activation status. Four genes of interest in this study, IL12A, IL12B, IL15, and IL23A, were not significantly different from control values. The initial studies also indicate MoMΦ can be included with dendritic cells and monocyte-derived dendritic cells for further analysis of the tri-directional signaling required for the development of CTL.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"46 ","pages":"e002723"},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10811724/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139572406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although adult dogs often remain asymptomatic when infected, there is limited published information concerning the laboratory and clinical findings and severity of infection in symptomatic adult dogs. Therefore, this study aimed to characterize the clinical and laboratory findings of adult Ancylostoma-infected dogs. Data were obtained by surveying the medical records of dogs treated at a University Veterinary Hospital from June 2009 to June 2019. Of 243 cases, 30 met the selection criteria. The most frequent clinical signs were diarrhea and hematochezia (13/30 each - 43.3%), and the most common laboratory findings were eosinophilia (13/30 - 43.3%), increased RDW (6/29 - 20.7%), and hypoalbuminemia (5/21 - 23.8%). Dogs with Ancylostoma spp. presented an increased proportion of high RDW (P= 0.010) compared with non-parasitized dogs. Dogs with higher fecal egg scores (n= 18) showed significantly lower RBC (6.26 ± 0.64 vs 7.24 ± 0.74 106/µL, P< 0.001) and albumin levels (2.8 ± 0.5 vs 3.2 ± 0.4 g/dL, P= 0.021), and an increased eosinophil count (1.42 ± 0.95 vs 0.58 ± 0.47 103/µL, P= 0.003) compared with the control group. Fecal egg scores exhibited a weak correlation with eosinophils (r = 0.42, P= 0.002) and a moderate correlation with RBC (r = -0.52, P< 0.001). In conclusion, despite relevant clinical signs, the laboratory findings were indicative of mild alterations in adult dogs, especially in those with lower scores of eggs in coproparasitological tests.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"46 ","pages":"e007724"},"PeriodicalIF":0.0,"publicationDate":"2024-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11734537/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143017401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surgical groups differed from each other in the Likert scale values for almost all the parameters regarding the difficulty of the surgical approaches (p < 0.05), with higher scores in the GCG group than in the GCP group. Based on the video recordings, the GCP group had higher scores than the GCG group for degrees of difficulty of the approach (p < 0.05).
