  • Title: [The problem of tissue parasitism].
    Author: Berezantsev IuA.
    Journal: Parazitologiia; 1982; 16(4):265-73. PubMed ID: 6750512.
    Abstract:
    Possessing a different antigenic structure larvae of helminths have to withstand the protective reactions of their hosts in order exist in their tissues. A new phenomenon was noted in host-parasite relationships. Larvae of helminths inhibit the host's leucocyte reaction (by inhibiting chaemotaxis) and induce the formation of a capsule of specific structure by the host. The capsules represent a modified protective reaction of the connective tissue. The capsules perform two main functions. They do not pass the specific antibodies from the host's blood to a parasite. They are physiologically active; an intensive transport of nutrients passes through them to the parasite against concentration gradient, with a participation of ferments and expenditure of energy.
