plasmacytoidní

Plasmacytoidní refers to a characteristic or property related to plasmacytoid cells. Plasmacytoid cells are a type of immune cell that shares features of both plasma cells and dendritic cells. They are primarily known for their ability to produce large amounts of type I interferons, particularly interferon-alpha (IFN-α), in response to viral infections or other immune stimuli. This potent cytokine production plays a crucial role in initiating and modulating the innate immune response, helping to control viral replication and alert other immune cells.

Plasmacytoid cells are found in various lymphoid tissues and circulate in the blood. Their presence is significant in the context of viral infections, autoimmune diseases like systemic lupus erythematosus, and certain types of cancer. The term "plasmacytoidní" might be used in a descriptive context to denote a cellular morphology resembling plasmacytoid cells, or to indicate a functional state characterized by interferon production, which is a hallmark of these cells. Understanding the plasmacytoidní nature of certain cellular processes or conditions is important for diagnosing and treating a range of immune-related disorders.
