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.
由于具有不同的抗原结构，蠕虫幼虫为了在宿主体内存活，必须抵御宿主的保护性反应。在宿主与寄生虫的关系中发现了一种新现象。蠕虫幼虫抑制宿主的白细胞反应（通过抑制趋化作用），并诱导宿主形成具有特定结构的包囊。这些包囊代表了结缔组织的一种改良的保护性反应。包囊具有两个主要功能。它们不会将宿主血液中的特异性抗体传递给寄生虫。它们具有生理活性；在酶的参与和能量消耗的情况下，营养物质通过它们以逆浓度梯度的方式大量输送到寄生虫体内。
