Human Mast Cell Line (LUVA)

Immortalized Human Mast Cell Line (LUVA) that is easily cultured without growth factors and that has a high expression of FceRI for investigating inflammation response.

Highlights:

  • Fast growing and increased life span, compared to typical blood-derived CD34+ cells
  • Proliferate independent of exogenous stem cell factors
  • Contain granules and express high levels of mast cell cytokines, prostaglandins and leukotrienes

Mast cells exist in several types of tissues and play a role in allergy and anaphylaxis as a factor in inflammation response. They are also involved in wound healing and defense against pathogens. These cells express the high-affinity receptors that are specific to IgE, FceRI, on their surface, making IgE molecules cell-surface receptors for an antigen. When bound IgE molecules find a substrate, mast cells release inflammatory mediators like histamine.

Comments

A difference has been noted in how the cells are behaving that is different from the original publication. In the article, LUVA cells had high levels of expression of FceRI, however levels of around 5% by cell surface staining are currently being observed. Higher levels with intracellular staining are seen and very high mRNA expression for FceRI is detected. The reason for this difference is not clear.
