Abstract
Studying cytokine profiling in Theleria annulata infection enhances our understanding of how the immune response unfolds, the intricate interactions between the host and the parasite, the strategies employed by the parasite to evade the immune system, and potential avenues for developing treatments. The generation of pro-inflammatory cytokines plays a pivotal role in the immune response against T. annulata infection. Elevated concentrations of these cytokines potentially contribute to the manifestation of clinical symptoms associated with the disease, such as fever, anemia, exophthalmia, and weight loss. The production of anti-inflammatory cytokines potentially serves as a regulatory mechanism for the immune response, preventing the development of severe disease. Nevertheless, in animals afflicted by T. annulata infection, there is often a notable decrease in the levels of these cytokines, suggesting that they may not be as effective in mitigating the disease as they are in uninfected animals. This knowledge can be harnessed to develop improved diagnostic methods, treatments, and vaccines for tropical theileriosis. The objective of this current mini review is to achieve the same goal by consolidating the available knowledge of cytokine interactions in Bovine Tropical Theileriosis (BTT).

Onzere CK, Bastos RG, Bishop RP, Suarez CE, Fry LM. Expression of IL-10 and TGF-β1 in horses experimentally infected with T. equi merozoites is associated with antibody production but not modulation of pro-inflammatory responses. Front Immunol 2024; 15:1370255. [PMID: 38803499 PMCID: PMC11128618 DOI: 10.3389/fimmu.2024.1370255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Accepted: 04/23/2024] [Indexed: 05/29/2024] Open
Abstract
Theileria equi (T. equi) is an apicomplexan parasite that causes severe hemolytic anemia in equids. Presently, there is inadequate knowledge of the immune responses induced by T. equi in equid hosts impeding understanding of the host parasite relationship and development of potent vaccines for control of T. equi infections. The objective of this study was to evaluate the host-parasite dynamics between T. equi merozoites and infected horses by assessing cytokine expression during primary and secondary parasite exposure, and to determine whether the pattern of expression correlated with clinical indicators of disease. Our findings showed that the expression of pro-inflammatory cytokines was very low and inconsistent during both primary and secondary infection. There was also no correlation between the symptoms observed during primary infection and expression of the cytokines. This suggests that the symptoms might have occurred primarily due to hemolysis and likely not the undesirable effects of pro-inflammatory responses. However, IL-10 and TGF-β1 were highly expressed in both phases of infection, and their expression was linked to antibody production but not moderation of pro-inflammatory cytokine responses.

A Genome-Wide Association Study for Resistance to Tropical Theileriosis in Two Bovine Portuguese Autochthonous Breeds. Pathogens 2024; 13:71. [PMID: 38251378 PMCID: PMC10819359 DOI: 10.3390/pathogens13010071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 01/03/2024] [Accepted: 01/09/2024] [Indexed: 01/23/2024] Open
Abstract
The control of Tropical Theileriosis, a tick-borne disease with a strong impact on cattle breeding, can be facilitated using marker-assisted selection in breeding programs. Genome-wide association studies (GWAS) using high-density arrays are extremely important for the ongoing process of identifying genomic variants associated with resistance to Theileria annulata infection. In this work, single-nucleotide polymorphisms (SNPs) were analyzed in the Portuguese autochthonous cattle breeds Alentejana and Mertolenga. In total, 24 SNPs suggestive of significance (p ≤ 10-4) were identified for Alentejana cattle and 20 SNPs were identified for Mertolenga cattle. The genomic regions around these SNPs were further investigated for annotated genes and quantitative trait loci (QTLs) previously described by other authors. Regarding the Alentejana breed, the MAP3K1, CMTM7, SSFA2, and ATG13 genes are located near suggestive SNPs and appear as candidate genes for resistance to Tropical Theileriosis, considering its action in the immune response and resistance to other diseases. On the other hand, in the Mertolenga breed, the UOX gene is also a candidate gene due to its apparent link to the pathogenesis of the disease. These results may represent a first step toward the possibility of including genetic markers for resistance to Tropical Theileriosis in current breed selection programs.

Parasite Immunol 2023; 45:e13002. [PMID: 37461131 DOI: 10.1111/pim.13002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 06/05/2023] [Accepted: 06/08/2023] [Indexed: 08/15/2023]
Abstract
In this study, we aimed to investigate haematological, pro-inflammatory, inflammatory, anti-inflammatory and immunological responses in naturally Theileria annulata-infected cattle. The study material consisted of 25 Simmental cattle, 2-4 years of age, one of which was a control group consisting of healthy animals (Control group, n = 10), and the other was a Theileria group that include animals positive for Theileria annulata (Theileria group, n = 15). Haematological analysis (red blood cell [RBC], haemoglobin [HGB], haematocrit [HCT]), pro-inflammatory (tumour necrosis factor-α [TNF-α], nuclear factor kappa B [NF-ĸB] and interleukin-1 beta, [IL-1β]), inflammatory (neutrophil-lymphocyte ratio [NLR]), anti-inflammatory (interleukin-10 [IL-10]) and antimicrobial peptide (CAMP) analyses were performed by using ELISA kit from blood samples. It was found that the rectal temperature of the Theileria group was found to be significantly higher (p < .001) than that of the control group. Haematological and biochemical analysis revealed that the RBC and HGB count and HCT percentage decreased (p < .001), while NF-ĸB (p < .001), TNF-α (p = .002), IL-1β (p < .001), IL-10 (p = .012), NLR (p < .001) and CAMP (p = .037) levels increased in Theileria group compared to the control group. There was a strong correlation between NF-ĸB and TNF-α, NF-ĸB and IL-10, NLR and IL-1β, NF-ĸB and CAMP, TNF-α and CAMP and IL-10 and CAMP. As a result of this study, it was revealed that a pro-inflammatory and immunological response also occurs along with the anti-inflammatory response in the inflammatory process.
