Abstract: | Summary A number of proteins, poly-L-amino acids, oligopeptides and lipids were tested for neutrophil, cosinophil and macrophage chemotactic activity. One myoglobin preparation was active. Based on the negative findings for all other substances, primary structure, secondary structure, degree of hydrophobicity, size and charge of a molecule, could be ruled out as structural features recognized by chemotactically responding phagocytes.I thank Dr J. H. Wissler for suggesting the reported experiments and Dr M. Landy and Prof. E. Sorkin for advice and criticism during preparation of this article. The excellent assistance by Mrs J. Kerschbaumer-Bech and Miss Margrit Bühlmann is gratefully acknowledged. This work was supported by Swiss National Foundation for Scientific Research, grant 3.8750.72, and by Sandoz-Stiftung, Basel. |
