Protection Against Nematodes by Intestinal Mucus
- 144 Downloads
Several lines of evidence suggest that intestinal mucus is involved in protection against nematode infections (Miller and Nawa, 1979). For example, Trichinella spiralis larvae become entrapped in mucus both in vivo in immune rats and in vitro (Lee and Ogilvie, 1980). Similarly, the immune expulsion of Njppostronqylus brasiliensis from rat intestine is accompanied by goblet cell hyperplasia and increased turnover of mucin (Miller et al., 1981). The experiments described here provide further information on the role of mucus in protection against N. brasiliensis.
