Interferon-gamma is produced by which cells
primarily by natural killer cells and T helper cells
Interferon-beta is produced by which cells
Fibroblasts
Interferon-alpha is produced by which cells
Interferon-alpha is produced by leucocytes
Monocytes are white blood cells that give rise to
macrophages and dendritic cells in the immune system. They produce cytokines such as IL-6 in response to infections and tissue injuries.

platelet transfusion in surgery targets
Platelet transfusion for thrombocytopenia before surgery/ an invasive procedure. Aim for plt levels of:
> 50×109/L for most patients
50-75×109/L if high risk of bleeding
>100×109/L if surgery at critical site
