Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) "isoform") that has been found only in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing four Ig-like constant domains (Cε1–Cε4). [1]
These cytokines mediate the activation of type 2 T helper cells (T h 2 cells), type 2 innate lymphoid cells (ILC2 cells), and dendritic cells. T h 2 cells and ILC2 cells secrete IL-4, IL-5 and IL-13. [1] [3] IL-4 further drives CD4+ T cell differentiation towards the T h 2 subtype and induces isotype switching to IgE in B cells.
Isogenic human disease models are a family of cells that are selected or engineered to accurately model the genetics of a specific patient population, in vitro.They are provided with a genetically matched 'normal cell' to provide an isogenic system to research disease biology and novel therapeutic agents.

Tumor-associated immune cells in the tumor microenvironment (TME) of breast cancer models. Cancer immunology (immuno-oncology) is an interdisciplinary branch of biology and a sub-discipline of immunology that is concerned with understanding the role of the immune system in the progression and development of cancer; the most well known application is cancer immunotherapy, which utilises the ...
The diagram above represents the process of chimeric antigen receptor T-cell therapy (CAR), this is a method of immunotherapy, which is a growing practice in the treatment of cancer. The final result should be a production of equipped T-cells that can recognize and fight the infected cancer cells in the body.
Each heavy chain has two regions: a constant region (which is the same for all immunoglobulins of the same class but differs between classes).. Heavy chains γ, α and δ have a constant region composed of three tandem (in a line next to each other) immunoglobulin domains but also have a hinge region for added flexibility.
Sharks also possess, as part of their adaptive immune systems, a functional heavy-chain homodimeric antibody-like molecule referred to as IgNAR (immunoglobulin new antigen receptor). IgNAR is believed to have never had an associated light chain, in contrast with the understanding that the heavy-chain-only antibodies in camelids may have lost ...
The following outline is provided as an overview of and topical guide to immunology: . Immunology – study of all aspects of the immune system in all organisms. [1] It deals with the physiological functioning of the immune system in states of both health and disease; malfunctions of the immune system in immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency ...
