From: Identification in milk of a serum amyloid A peptide chemoattractant for B lymphoblasts
Chemoattractant activity of whey with lymphoid cells, before (▲ – ▲) and after 10 kDa PES membrane ultrafiltration (■ – ■). Swine B-cell lymphoblasts (A), lymphocytes from the MLN (B) and from the ILN (C). Spontaneous and fMLP (10-6 M)-induced migrations are indicated by horizontal lines. In the insert: Absence of chemotactic activity of ultra-retentate onto B lymphoblasts. The results are expressed as the mean number of adherent cells per 4 HPF in 3 independent experiments (except with ILN (n = 6)), each performed in triplicate (*p < 0.05 versus spontaneous migration).
