Peripheral mononuclears under normal hemopoiesis and after chemotherapy or/and cytokin were isolated on blood cell separator and cryopreserved. The cells from 22 patients with different hematological and solid malignancies were examined. Mononuclears with high content of hemopoiesis precursors may be collected rapidly after stimulation. Fast and persistent recovery of hemopoiesis in transplantation of this material after superhigh-dose chemotherapy of prognostically unfavourable patients is demonstrated. Cytokin (granulocytic and granulocytic-macrophagal growth factors) promoted fast and reliable production of sufficient quantities of peripheral blood hemopoiesis cells precursors.

Background: This study aimed to investigate miRNAs and upstream regulatory transcription factors involved in schizophrenia (SZ) pathogenesis.
Methods: Differential expression of miRNAs and genes in SZ patients was investigated utilizing the gene expression omnibus dataset, gene ontology annotations, and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. Real-time quantitative polymerase chain reaction experiments were conducted to validate the predictive screening of regulatory genes in peripheral blood samples from 20 SZ patients and 20 healthy controls.

People with HIV (PWH) have an elevated risk of cardiovascular disease compared to those without HIV. This study aimed to investigate the relative serum expression of microRNAs (miRNAs) associated with arterial stiffness, a significant marker of cardiovascular disease. A total of 36 male PWH and 36 people without HIV, matched for age, body mass index, pack years, and dyslipidemia, were included in the study.

Mandarin fish ranavirus (MRV) is a distinctive member among the genus of the family . The persistently covert infection of MRV was previously observed in a natural outbreak of MRV, but the underlying mechanism remains unclear. Here, we show that mandarin fish peripheral B lymphocytes are implemented as viral reservoirs to maintain the persistent infection.

Robust CD8 T cell responses are critical for the control of HIV infection in both adults and children. Our understanding of the mechanisms driving these responses is based largely on studies of cells circulating in peripheral blood in adults, but the regulation of CD8 T cell responses in tissue sites is poorly understood, particularly in pediatric infections. DNA methylation is an epigenetic modification that regulates gene transcription.

The mechanisms of the innate immunity control of equine infectious anemia virus in horses are not yet widely described. Equine monocytes isolated from the peripheral blood of three Equine infectious anemia (EIA) seronegative horses were differentiated in vitro into macrophages that gave rise to mixed cell populations morphologically referable to M1 and M2 phenotypes. The addition of two equine recombinant cytokines and two EIA virus reference strains, Miami and Wyoming, induced a more specific cell differentiation, and as for other species, IFNγ and IL4 stimulation polarized horse macrophages respectively towards the M1 and the M2 phenotypes.
