Monocyte and dendritic cell defects in COVID-19

چکیده
Monocytes, plasmacytoid and conventional dendritic cells are crucial for antiviral immune responses. A new study now compares severe moderate cases of COVID-19 links defects in viral sensing, interferon antigen presentation pathways, associated with upregulated apoptosis inflammatory to high severity.

Efficiency and Impact of Positive and Negative Magnetic Separation on Monocyte Derived Dendritic Cell Generation
Background: The immunomagnetic separation technique is the basis of monocyte isolation and further generation of monocyte-derived dendritic cells. Objective: To compare the efficiency of monocyte positive and negative separation, concentration of beads, and their impact on generated dendritic cells. Methods: Monocytes were obtained using monoclonal antibody-coated magnetic beads followed the Fi...
متن کاملGeneration of Mature Monocyte-Derived Dendritic Cells in the Presence of Heparin and Monocyte Conditioned Medium: Phenotypic and Functional Comparison
Background: Dendritic cells (DC) induce tumor or pathogen-specific T cell responses in humans. Several laboratories have developed culture systems, including maturation factors for human DC from peripheral blood monocytes. We comprehensively compared standard maturation stimulus, an autologous monocyte-conditioned medium (MCM), with heparin for their ability to promote uniformly mature DC that ...
متن کاملDIFFERENTIATION OF MONOCYTE DERIVED DENDRITIC CELLS IN SERUM FREE CONDITIONS
Human peripheral blood monocytes (HPBM) were cultured in the absence of human serum and were converted into a state exhibiting a high accessory function expressed by their ability of supporting lymphocyte proliferation. After a prolonged culture in serum free media the monocyte derived cells were highly viable, increased in size and developed veils and dendritiform elongatio'l1s. Paralleli...
متن کاملMaturation State and Function of Monocyte Derived Dendritic Cells in Liver Transplant Recipients
Background: Dendritic cells (DCs) are potent antigen presenting cells for triggering of the immune reaction post transplantation. These cells are centrally involved in the initiation of T cell-dependent immune responses. Objective: To compare the level of DC maturation and function in liver transplant recipients with healthy controls. Methods: In this study, twelve peripheral blood samples we...
متن کاملDendritic cell defects in the colorectal cancer
Colorectal cancer (CRC) results from the accumulation of both genetic and epigenetic alterations of the genome. However, also the formation of an inflammatory milieu plays a pivotal role in tumor development and progression. Dendritic cells (DCs) play a relevant role in tumor by exerting differential pro-tumorigenic and anti-tumorigenic functions, depending on the local milieu. Quantitative and...
