Human Cord Blood Naive T Helper Cells, CD4+

Description

Human Peripheral Blood CD4⁺ T Helper Cells are primary immune cells isolated from the peripheral blood of healthy human donors. These cells represent a heterogeneous population of mature CD4⁺ T lymphocytes, comprising naïve and memory subsets that have undergone physiological immune maturation in vivo. Functionally, CD4⁺ T helper cells play a central role in adaptive immunity by coordinating immune responses through cytokine secretion and cell–cell interactions. They provide essential help to B cells for antibody production, support CD8⁺ T cell activation and differentiation, and regulate innate immune cells such as macrophages and dendritic cells. These cells typically express characteristic surface markers including CD3 and CD4 and grow in suspension under standard culture conditions. Human peripheral blood CD4⁺ T helper cells are widely used in immunology research to study T cell activation, cytokine signaling, immune regulation, inflammatory responses, and disease-related immune dysfunction in infection, autoimmunity, and cancer research.
