Granuloma formation around filarial larvae triggered by host responses to an excretory/secretory antigen.

In previous studies using a murine model of filarial infection, granuloma formation was found to be a most important host-protective mechanism. We have also shown that in vitro cytoadherence is a surrogate for the formation of antifilarial granulomas in vivo and that it requires "alternatively activated" host cells and a source of antifilarial antibody. We show here that antibodies against L3 excretory/secretory (E/S) products can facilitate in vitro cytoadherence.

Beyond MEDLINE for literature searches.

Purpose: To describe strategies for a comprehensive literature search.

Organizing Construct: MEDLINE searches result in limited numbers of studies that are often biased toward statistically significant findings. Diversified search strategies are needed.
