General description

Interleukin-1α (IL-1α) is a cytokine that belongs to the interleukin-1 (IL-1) family. It is located intracellularly in hematopoietic and non-hematopoietic cells. IL-1α gene is located on the human chromosome at 2q14.1.

Application

Interleukin-1α (IL-1α) has been used:
  • to study its effects on human colorectal adenocarcinoma cells
  • to stimulate primary human fetal retinal pigment epithelium (hfRPE) cells
  • to pre-stimulate human THP-1 monocytes

Biochem/physiol Actions

Interleukin-1α (IL-1α) plays a crucial role in inflammation during cell necrosis. It also regulates the recruitment of interleukin-1β (IL-1β), neutrophils, chemokines, and other cytokines at the site of injury. IL-1α exhibits a dual function of binding to its cell surface receptor as well as chromatin.

Physical form

Lyophilized from 0.2 μm filtered 10 mM sodium phosphate , pH 8.0, plus 50 mm NaCl and 50 μg bovine serum albumin (BSA) per μg cytokine.

Analysis Note

The proliferative activity of human IL-1α is tested in culture using the murine cell line D10S.

Inflammation occurs after disruption of tissue homeostasis by cell stress, injury or infection and ultimately involves the recruitment and retention of cells of hematopoietic origin, which arrive at the affected sites to resolve damage and initiate repair. Interleukin 1α (IL-1α)

Interleukin Family (IL)

The Interleukins comprise a disparate group of cytokines and growth factors that are produced by and released from leukocytes. Interleukin-1β (1L-1β) is released primarily from stimulated macrophages and monocytes and plays a key role in inflammatory and immune responses and may induce anti-tumor immunity.
