Examining how leukocytic pyrogen and epidermal cell thymocyte-activating factor attract immune cells, linking inflammation and fever.

The study aims to investigate the chemotactic activity of leukocytic pyrogen and epidermal cell thymocyte-activating factor in neutrophil response.
Investigated the pyrogenic activity of ETAF and LP in relation to PMN chemotaxis.
Purified ETAF and LP using column chromatography and isoelectric focusing.
Measured the chemotactic activity and blocked it with an anti-LP antibody.
ETAF and LP exhibited chemotactic activity for PMN, correlating with fever-inducing effects (p<0.05).
Maximal chemotactic activity was linked to peak thymocyte-activating activity.
Chemotactic activity was inhibited by an antibody against LP.

Sauder et al. (1984) studied this question.
