Lack of correlation between mast cell response and active anaphylaxis in mice

International Archives of Allergy and Applied Immunology

Abstract

Mast cell-competent mice, sensitized to lysozyme, were examined for their mast cell and anaphylactic responses to determine whether anaphylactic shock could occur independent of mast cell participation. Tissues (cremaster muscle, subdermal connective tissue and mesentery), taken a short time after intravenous antigenic challenge, showed no evidence of mast cell degranulation above control tissues. Data obtained from a quantitative comparison of the onset and increase in local and systemic anaphylactic and mast cell sensitivities to the antigen provide strong support for the view that mast cells are not the major effector cells for systemic anaphylaxis in mice. The significant increase in blood pressure that occurred immediately after infusion with the antigen also indicates that other cells within the blood stream are involved.

Bacterial Cell Wall Structure

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.
