Effects of latent infection of Toxoplasma gondii strains with different genotypes on mouse behavior and brain transcripts.

Background: Toxoplasma gondii can cause severe damage to immunodeficient hosts, and also compromise brain structure and function in immunocompetent hosts during latent infection. In China, the two different isolates, Chinese I (ToxoDB#9) and Chinese III are dominant epidemic strains widely spreading in humans and domestic animals and can lead to latent infection in host brain tissues, but the comparison of their manipulation patterns and mechanisms remains unclear.

Methods: Tachyzoites of the TgWh6 (Wh6) strain and the TgCtLHG (LHG) strain were used for establishing in vitro infection models within mouse microglia BV2 cells, and the differences in their invasion and proliferation patterns were observed.

Background: Esophageal cancer (ESCA) poses a significant challenge in oncology because of the limited treatment options and poor prognosis. Therefore, enhancing the therapeutic effects of radiotherapy for ESCA and identifying relevant therapeutic targets are crucial for improving both the survival rate and quality of life of patients.

Aim: To define the role of the transcription factor Snail family transcriptional repressor 1 (SNAI1) in ESCA, particularly its regulation of radiosensitivity.

Therapeutic importance of hydrogen sulfide in cognitive impairment diseases.

The brain naturally synthesizes hydrogen sulfide (HS) via enzymes such as cystathionine-β-synthase (CBS), 3-mercaptopyruvate sulfurtransferase (3-MST), cysteine aminotransferase (CAT), and cystathionine-γ-lyase (CSE). From a physiological point of view, HS serves as a neuromodulator with antioxidant and neuroprotective properties. Recent research suggests that HS is crucial in regulating learning and memory, as its downregulation is commonly observed in cognitive impairment diseases.

Anti-echinococcal effect of verapamil involving the regulation of the calcium/calmodulin-dependent protein kinase II response in vitro and in a murine infection model.

Background: Echinococcosis, which is caused by the larvae of cestodes of the genus Echinococcus, is a parasitic zoonosis that poses a serious threat to the health of humans and animals globally. Albendazole is the drug of choice for the treatment of echinococcosis, but it is difficult to meet clinical goals with this chemotherapy due to its low cure rate and associated side effects after its long-term use. Hence, novel anti-parasitic targets and effective treatment alternatives are urgently needed.

Contributions and achievements on schistosomiasis control and elimination in China by NIPD-CTDR.

Being a zoonotic parasitic disease, schistosomiasis was widely spread in 12 provinces of Southern China in the 1950s, severly harming human health and hindering economic development. The National Institute of Parasitic Diseases at the Chinese Center for Diseases Control and Prevention, and Chinese Center for Tropical Diseases Research (NIPD-CTDR), as the only professional institution focussing on parasitic diseases at the national level, has played an important role in schistosomiasis control in the country. In this article, we look back at the changes of schistosomiasis endemicity and the contribution of NIPD-CTDR to the national schistosomiasis control programme.

Mapping the epitopes of Schistosoma japonicum esophageal gland proteins for incorporation into vaccine constructs.

Background: The development of a schistosome vaccine has proved challenging but we have suggested that characterisation of the self-cure mechanism in rhesus macaques might provide a route to an effective product. The schistosome esophagus is a complex structure where blood processing is initiated by secretions from anterior and posterior glands, achieved by a mixture of ~40 unique proteins. The mechanism of self-cure in macaques involves cessation of feeding, after which worms slowly starve to death.

This paper reports a case of human thelaziasis callipaeda in Tongren area of Guizhou Province.

[Histone ubiquitylation and its roles in DNA damage response].

Ubiquitylation is an essential type of protein post-translational modifications (PTMs) in eukaryotes, which mediates various biological processes by regulating the subcellular localization, activity, and stability of proteins. Histones, as the main protein ingredients of chromatin, are closely coupled with DNA activities such as replication, transcription and repair, and therefore are the hotspots of PTMs. After DNA damage, histone ubiquitylations are involved in DNA damage response (DDR) by regulating nucleosome structure, activating cell cycle checkpoints, remodeling the nucleosome, and the recruitment and assembly of repair factors.

Pro-Angiogenic Activity of Monocytic-Type Myeloid-Derived Suppressor Cells from Balb/C Mice Infected with Echinococcus Granulosus and the Regulatory Role of miRNAs.

Background/aims: This study aims to predict the pro-angiogenic functions of monocytic-type myeloid-derived suppressor cells (M-MDSCs) derived from mice infected with Echinococcus granulosus.

The excretory-secretory products of Echinococcus granulosus protoscoleces stimulated IL-10 production in B cells via TLR-2 signaling.

Background: Excretory-secretory products released by Echinococcus granulosus protoscoleces (EgPSC-ESPs) are well-known to regulate T cell responses. However, their direct influence on the differentiation of B cell subsets remains largely elusive. This study investigated the effects of EgPSC-ESPs on the differentiation of IL-10-producing B cells (B10), and explored the possible role of Toll-like receptor 2 (TLR-2) signaling in this process.

Methods: The hydatid cysts and protoscolex derived from experimentally infected mice were collected and cultured , then the human umbilical vein endothelial cells were stimulated by the supernatant and cyst fluid respectively, and the angiogenesis was observed and analyzed through a microscope and the angiogenesis mode of the software NIH Image J. Meanwhile, the mouse homologous proteins of matrix metalloproteinase-9 (MMP-9) and high mobility group box B1 (HMGB1) were identified in genome through sequence alignment, and their transcriptional levels in the cyst wall and protoscolex were analyzed.

Microexon gene transcriptional profiles and evolution provide insights into blood processing by the Schistosoma japonicum esophagus.

Background: Adult schistosomes have a well-developed alimentary tract comprising an oral sucker around the mouth, a short esophagus and a blind ending gut. The esophagus is not simply a muscular tube for conducting blood from the mouth to gut but is divided into compartments, surrounded by anterior and posterior glands, where processing of ingested blood is initiated. Self-cure of rhesus macaques from a Schistosoma japonicum infection appears to operate by blocking the secretory functions of these glands so that the worms cease feeding and slowly starve to death.
