#leukocytes

• Aleukocytosis — A rare pathological condition characterized by the total absence or extreme, critical, and potentially fatal decrease of leukocytes (white blood cells) in the peripheral blood. It represents a severe manifestation of bone marrow aplasia or major hematopoietic disorders, exposing the organism to an imminent risk of massive opportunistic infections due to the complete collapse of the immune system.
• Autoleukocytotherapy — An advanced therapeutic method consisting of harvesting, isolating, processing, or activating in the laboratory leukocytes (white blood cells) from a patient's own blood, followed by their reintroduction into their organism. Used in cancer immunotherapy or in treating severe infectious and autoimmune conditions, this autologous medical procedure aims to stimulate, reconfigure, or amplify the immune system's natural defense capacity against tumor cells or pathogens.
