A Babesia microti-like rodent parasite was isolated from the tick, Ixodes persulcatus, collected from the northern forest area of Heilongjiang province, China. The collected I. persulcatus were allowed to feed on specific pathogen-free SCID mice and red blood cells from the mice were used to isolate Babesia spp. with the microareophilous stationary-phase(More)
In China, the ability of Ixodes persulcatus, Haemaphysalis concinna and Dermacentor silvarum to transmit Borrelia spirochetes was determined under laboratory conditions. Results showed that all three tick species can acquire spirochetes by feeding on infected mice. However, the capability of the three species to maintain spirochetes was different. Only I.(More)
BACKGROUND AIMS Mounting evidence shows that non-cell-based transplantation of exosomes derived from mesenchymal stromal cells (MSCs) has more potential protective and reparative effects than MSCs have. However, whether it is safe to transplant MSC exosomes into tissues is still not clear. In this study, we evaluated the safety of transplantation of(More)
In order to determine the principal vectors of Lyme disease in South China, the capability of Ixodes sinensis to transmit Lyme disease spirochetes transstadially was estimated in the laboratory. Results suggest that I. sinensis can acquire active Lyme disease spirochetes by feeding on infected mice of Kunming strains (KM), and the positive rates of larvae(More)
Total 24 valid species belongs to 6 subgenera in genus Ixodes had been documented in China. Of them, Eschatocephalus (2 species), Scaphixodes (2 species); Partipalpiger (1 species), Pholeoixodes (3 species) Ixodiopsis (1 species) and the largest subgenus Ixodes (15 species) were involved. Fortunately, we found another 3 new record species, namely I.(More)
OBJECTIVES Gastric cancer mesenchymal stem cells (GC-MSCs) can promote the development of tumour growth. The tumour-promoting role of tumour-associated MSCs and T cells has been demonstrated. T cells as the major immune cells may influence and induce a pro-tumour phenotype in MSCs. This study focused on whether CD4+ T cells can affect GC-MSCs to promote(More)
