In the periphery, co-stimulation rescues a T cell. In the thymus, the same molecules kill it. A peripheral T cell that engages its receptor without CD80 and CD86 becomes anergic; engage them and it r

The mast cell is loaded long before the allergen arrives. IgE bound to FcεRIα is not waiting to be recruited the way an antibody waits for antigen in a serum assay — it is already installed on the ce

The human body is a complex and intricate system where various components work together to maintain health and combat potential threats. Among these essential players are the TNF cyt

The germinal centre is where antibody quality is made. A naive B cell that binds antigen does not become a source of protective, high-affinity IgG by accident. It passes through a tightly choreograph

Transplant rejection is the fastest, most violent adaptive immune response a body can mount — and it is a response to a molecule rather than to a pathogen. Somewhere between one and ten per cent of a

Interleukin-9 (IL-9) plays a critical role in the immune system, influencing a variety of biological functions across different immune cell types. This article provides an in-depth look at the sig

Immunophenotyping by Flow Cytometry Immunophenotyping is a technique used in the field of immunology and cell biology to identify and classify cells based on the specific proteins o

Immunology · Antigen PresentationDendritic Cells: Markers, Activation and SubtypesDendritic cells are the professional antigen-presenting cells that decide whether an immune response happens at all. T

What is a Plasma Membrane? The plasma membrane, also known as the cell membrane, is a vital component of all cells. It is a thin, semi-permeable barrier that separate

By Charlotte O'Donnell PhD The genes of the IL-36 family members are located in a cluster on chromosome 2 [1]. All three activating ligands, IL-36α, IL-36β a

Immunology · T LymphocytesCD8+ T Cells: Cytotoxic Mechanisms, Memory and ExhaustionCD8+ T cells kill infected and transformed cells directly, and they do it with a specificity nothing else in the immu

Immunology · Flow CytometryT Cell Immunophenotyping: Markers, Subsets and Panel DesignImmunophenotyping identifies cell populations by the proteins on their surface. For T cells that means resolving n

Un isotipo es la clase de inmunoglobulina que define la región constante de su cadena pesada, y el organismo humano produce cinco: IgG, IgA, IgM, IgD e IgE. Cada uno tiene una forma distinta, apar
