The study aimed to evaluate and compare haematological changes and distinct pro and anti-inflammatory cytokine profiles between anti-Toxoplasma seropositive and seronegative in post-abortive women. The enzyme-linked immunosorbent assay (ELISA) was performed to examine serum samples from 224 post-abortive women for anti-Toxoplasma immunoglobulin M (IgM) and G (IgG) antibodies. Besides serum cytokines such as Tumour Necrosis Factor α (TNF-α), interleukin 10, 12 (IL-10, IL-12), and Transforming Growth Factor ß1 (TGFß1) were evaluated. Also, the blood groups and haematological parameters were examined. The overall anti-Toxoplasma seropositivity was 25% (56/224), including 19.6% for IgG and 5.4% for IgM, with highly (p < 0.001) significant variations. Blood group type significantly affected IgG and IgM seropositivity rates (p = 0.003 and p = 0.004) individually. IgG seropositivity displayed significant differences in Granulocyte (GRA) p = 0.003, Haemoglobin (Hb) p = 0.009, Mean Platelet Volume (MPV) p = 0.004, and Red Blood Cell (RBC) p = 0.008, whilst IgM seropositivity displayed significant differences of Hb p = 0.019 plus RBC p < 0.001. Besides, IL-12 was significantly higher (p < 0.001) in comparison to controls.

CD163 is frequently used as an M2-associated marker in chronic helminth infections. This study evaluated whether the CD163:CD68 ratio can serve as a semi-quantitative indicator of macrophage polarisation in schistosomal splenomegaly. Forty female CD-1 mice were divided into infected and control groups, and spleens were collected at 7-, 15-, and 23-weeks post-infection. Histopathology and immunohistochemistry for CD68 and CD163 were quantified in five high-power fields per animal. Semi-quantitative scoring, percentage positivity, CD163:CD68 ratios, and correlations with pathological severity were analysed. Chronic infection caused progressive splenic pathology, including white pulp atrophy, red pulp congestion, fibrous septa, extramedullary haematopoiesis, and hemosiderin-laden macrophages. CD68⁺ macrophages increased significantly from 20% to 30% in controls to 70%-85% at 23 weeks (p < 0.001), while CD163 expression declined from 49.3% in naïve spleens to nearly zero at all post-infection time points. The CD163:CD68 ratio fell from 1.97 to near zero. CD163 correlated negatively with CD68 (ρ = -0.891) and pathology severity (ρ = -0.876), whereas CD68 showed a strong positive correlation (ρ = +0.912). Chronic S. mansoni infection induces a profound, early, and sustained downregulation of CD163 expression on splenic macrophages despite expansion of the total macrophage pool. While CD163 loss associates with splenic congestion, iron accumulation, and architectural remodelling, the functional implications of this change remain to be fully defined. We therefore propose that disruption of CD163-dependent homeostatic programmes may contribute to splenic pathology, a hypothesis that warrants future functional and multi-marker validation in line with current concepts of macrophage plasticity.</p>","PeriodicalId":19931,"journal":{"name":"Parasite Immunology","volume":"48 3","pages":"e70075"},"PeriodicalIF":2.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147459208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, we investigated the expression changes of sialidases (Neu1, Neu2, and Neu3) and sialyltransferases (ST3Gal1, ST3Gal5, and ST6Gal1) in the spleen and liver of L.d- infected BALB/c mice using droplet digital polymerase chain reaction.

We observed downregulation of all sialidases (Neu1, Neu2, and Neu3) in contrast to an upregulation of sialyltransferases-ST3Gal1 and ST3Gal5. Notably, splenic sialidases exhibited a strong negative correlation with A2 (Neu1: r = -0.81, Neu2: r = -0.78), suggestive of reduced desialylation. Conversely, both the sialyltransferases ST3Gal1 and ST3Gal5 strongly positively correlated with A2 (r = 0.81, r = 0.89 respectively).

We aimed to identify the host genetic factors controlling protoscolex development and maturation in congenic mice carrying susceptible DBA/2 genomic segments on a resistant C57BL/6N background. We assessed the hepatic protoscoleces and immune-related gene expression levels 16 weeks post-oral infection. All congenic strains developed protoscoleces; however, the number and proportion of mature forms decreased as C57BL/6N-derived genomic contribution on chromosome 1 increased. Differences in DBA/2-derived segments revealed two loci, E. multilocularis protoscolex maturation 1 (Empmat1) and 2 (Empmat2), as regulators of protoscolex maturation, but not early development, where immune involvement was limited. T-box transcription factor 21 expression was correlated with protoscolex maturation; however, it lay outside Empmat1 and Empmat2 and was unlikely to be the responsible gene. Therefore, protoscolex maturation is potentially regulated by multiple host genetic factors distinct from those involved in early development, with B6-derived alleles exerting inhibitory effects, possibly via non-immune host mechanisms. Elucidation of these genetic pathways can reveal novel targets to disrupt the life cycle and reduce the zoonotic transmission of E. multilocularis.</p>","PeriodicalId":19931,"journal":{"name":"Parasite Immunology","volume":"48 2","pages":"e70065"},"PeriodicalIF":2.1,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146207107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infected mice under a standard diet or ADF showed higher egg deposition and larger pulmonary granulomas than HSD or PZQ-treated animals. Inflammatory infiltrate and alveolar collapse were more intense in INF and ADF groups, while macrophage accumulation increased with ADF but decreased after PZQ. Pulmonary fibrosis was reduced in ADF, HSD and PZQ groups compared to INF, though higher in ADF than in HSD or PZQ.

In RAG1- and RAG1/γc-deficient mice, infection persisted under a normal diet but worm burdens were partially reduced on HFD, indicating that diet enhances parasite control through immune-independent, possibly microbiota-mediated pathways.

Essential trace elements such as iron, zinc, copper and magnesium play pivotal roles in immune regulation, antioxidant defence, and pathogen control. However, their alterations during malaria infection and implications for disease outcome have been inconsistently reported. This systematic review aimed to synthesise current evidence on serum and plasma concentrations of key trace elements in malaria-infected individuals and experimental models, and to evaluate their relationship with immune responses, disease severity, and treatment outcomes. A systematic search was conducted in various academic databases, including PubMed, Web of Science, Scopus, and Google Scholar for studies published from January 2010 to November 2025. The quality assessment of the studies was done using the Critical Appraisal Skills Programme (CASP) tool. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to ensure a comprehensive and transparent process. Across human and experimental studies, malaria infection was consistently associated with reduced serum concentrations of iron, zinc, and magnesium, while copper levels showed variable trends, often elevated in acute infection, reflecting an inflammatory response. These alterations were linked to dysregulated cytokine production, particularly increased TNF-α and IL-10, higher parasitemia, and worsened clinical outcomes. Zinc supplementation improved micronutrient status but showed limited impact on malaria incidence. Emerging spectrometric approaches demonstrated utility in trace element profiling for malaria diagnosis and prognosis. Malaria-induced disturbances in trace element homeostasis, notably reduced iron, zinc, and magnesium, and altered copper levels, contribute to immune dysfunction and oxidative stress, aggravating disease severity.
