Specific IgE was determined with the rat passive cutaneous anaphylaxis test using a conjugate of 2,4-D with bovine serum albumin for challenge.

One day post-challenge, the mice were processed to obtain biologic materials for use in assays of total IgE levels in serum and bronchoalveolar lavage fluid (BALF); differential cell counts and chemokine levels in BALF; lymphocyte counts and surface antigen expression on B-cells within regional lymph nodes (LNs); and, ex situ cytokine production by cells from these LNs. 2,4-D-induced immune responses characteristic of immediate-type respiratory reactions, as evidenced by increased total IgE levels in both serum and BALF; an influx of eosinophils, neutrophils, and chemokines (MCP-1, eotaxin, and MIP-1beta) in BALF; increased surface antigen expression on B-cells IgE and MHC class II production) in both auricular and the lung-associated LNs; and increased Th2 cytokine production (IL-4, IL-5, IL-10, and IL-13) in both auricular and the lung-associated LN cells.

Toxicol Lett. 2010 Feb 26.

Our aim was to improve a method for detecting respiratory hypersensitivity by testing three confirmed respiratory allergens (trimellitic anhydride [TMA], phthalic anhydride [PA] and toluene diisocyanate [TDI]), an environmental chemical of uncertain allergenicity (2,4-d-butyl [DB]), a confirmed contact allergen (2,4-dinitrochlorobenzene [DNCB]) and a standard irritant (sodium dodecyl sulfate [SDS]).
One day post-challenge, samples were taken from the mice to assay for total immunoglobulin (IgE and IgG (1)) levels in serum and bronchoalveolar lavage fluid (BALF); differential cell counts and cytokine/chemokine levels in BALF; lymphocyte counts and surface antigen expression on B-cells within lung-associated lymph nodes (LNs); ex situ cytokine production by cells from these LNs; and gene expression in BALF (CCR3) and LNs (CCR4, STAT6 and GATA-3).
