Summary: The study demonstrated the significant prophylactic effects of ASEO in increasing survival rate and reducing parasite load in mice with acute toxoplasmosis. ASEO also promoted the innate immune system, regulation of pro-inflammatory cytokines, and inhibition of hepatic injury in the infected mice. Further research is needed to fully understand the prophylactic and therapeutic mechanisms of ASEO against Toxoplasma.

Summary: Genotype analysis of Toxoplasma gondii reveals high genetic diversity among strains from different hosts and origins. Non-archetypal genotypes found in wild hosts in South America are associated with severe multivisceral toxoplasmosis and high mortality in immunocompetent individuals. This review discusses the potential of using specific antibodies produced during T. gondii infection as biomarkers to identify infecting genotypes, while highlighting the complexity and difficulty due to the genetic diversity organized into 16 haplogroups and 6 major clades.

Summary: The study evaluated the antiparasitic effect of chloroquine (CQ), spiramycin (SP), and their combination against Toxoplasma gondii (T. gondii) and found that the combination of CQ and SP was more efficient than using SP alone. The combination treatment induced apical disruption of tachyzoites and triggered host cell apoptosis by increasing relative caspase 3 gene expression and suppressing Bcl-2 and XIAP. Additionally, the combination treatment upregulated IFN-gamma level, reduced serum AST and ALT, and ameliorated liver inflammation.

Summary: This study observed the changes in cardiac functions after T. gondii infection and assessed the damage caused by reactivation. The results showed that cardiac functions were impaired in acute and reactivation groups, with myocardial fibrosis and diastolic dysfunction occurring in the chronic stage. Reactivation infection exacerbated cardiac damage and was associated with macrophage activation, myocardial fibrosis, and impaired antioxidant capacity.

Summary: Neuroimmune interactions are crucial for tissue defense, organ homeostasis, and organismal physiology. Neuronal and immune cell subsets can colocalize in tissues, forming neuroimmune cell units that drive coordinated responses to signals. Recent studies show how these interactions maximize sensing of environmental aggressions and modulate immune function in health and disease.

Summary: Cytokines play a key role in the immune system and are essential for resisting infections like toxoplasmosis. The balance between pro-inflammatory and anti-inflammatory cytokines is crucial, as excessive production of pro-inflammatory cytokines can lead to tissue damage and enhance the proliferation of Toxoplasma. Immunosuppressed patients are more susceptible to toxoplasmosis. Studying the mechanisms of cytokine secretion and action could provide insights for the treatment and prevention of Toxoplasma infection.

Summary: Mixed parasitic infections can affect the host immunological responses and alter the pathogenesis of each other. This study investigated the impact of chronic trichinellosis on immune response to T. gondii infection. The results showed that prior infection with T. spiralis attenuated the Th1 response to T. gondii, leading to improved histopathological changes in the tissues.

Summary: In this study, the researchers found that ICAM-1 is expressed on the sinus endothelia of lymph nodes, but not on the lymphatic vessels of peripheral tissues. Memory CD4(+) T cells migrated to lymph nodes from peripheral tissues more efficiently than from blood vessels. ICAM-1 deficiency significantly inhibited the migration of lymphocytes from peripheral tissues into lymph nodes, and the absence of ICAM-1 or LFA-1 reduced the number of memory T cells in lymph nodes.

Summary: Lumpy skin disease virus (LSDV) is of high economic importance and has spread rapidly to many European and Asian countries in recent years. In 2020, an LSDV strain (GD01/2020) was discovered in a cattle farm in Guangdong, China, showing typical LSD symptoms. Genomic analysis revealed that GD01/2020 was highly similar to LSDVs isolated in Xinjiang, China in 2019, but distinct from LSDVs identified in other countries. This recombinant strain may affect the virulence and transmissibility of the virus, and its origin remains unknown.

Summary: We report the sequencing, assembly, and annotation of the 3.16 gigabase genome of the tick Haemaphysalis longicornis. The genome of this species is larger than the previously assembled one and contains a high proportion of simple sequence repeats. Through genomic analysis, key genes involved in iron metabolism, detoxification, and freeze tolerance of H. longicornis were identified. Additionally, numerous endogenous viral elements were found within the genome. These findings provide insights into the genetic mechanisms of specific biological processes in ticks and lay the foundation for integrated control of ticks and tick-borne diseases.

Summary: The study found that the GP900 protein is present in sporozoites and intracellular meronts, but absent in sexual stages. It is stored in the micronemes of sporozoites but enters the secretory pathway during excystation and invasion. GP900 is cleaved in the secretory pathway before reaching the extracellular space, implying its main role as a lubricant.

Summary: This study analyzed succinylproteomics of SARS-CoV-2 infection using quantitative mass spectrometry, revealing significant changes in succinylation on host and viral proteins. SARS-CoV-2 infection promotes succinylation of key enzymes in the TCA, leading to inhibition of cellular metabolic pathways. The viral nonstructural protein NSP14 regulates host protein succinylation through interaction with SIRT5, and succinylation inhibitors show antiviral effects. Succinylation modification is also observed on SARS-CoV-2 nucleocapsid and membrane proteins, as well as its variants.

Summary: This is the first reported case of tick-borne Rickettsia aeschlimannii infection in a woman from Xinjiang, northwestern China. The infection was confirmed by molecular detection in the patient's blood and urine, and she presented severe edema, partial necrosis, and monocytosis as clinical symptoms. R. aeschlimannii was also found in Hyalomma asiaticum ticks around the patient's residence. Infections of spotted fever group Rickettsia species should be considered in the differential diagnosis of tick-borne diseases.
