Association of a Gene Polymorphism with Chronic Lymphatic Filariasis in a South Indian Cohort.

Lymphatic filariasis (LF) is a parasitic infection, caused by three closely related nematodes, namely , , and . Previously, we have shown that lysate from microfilariae induces the expression of interleukin and programmed death-ligand on monocytes, which lead to inhibition of CD4 T-cell responses. In this study, we investigated associations of and programmed cell death pathway gene polymorphisms with clinical manifestation in LF.

Diplomatic Assistance: Can Helminth-Modulated Macrophages Act as Treatment for Inflammatory Disease?

Helminths have evolved numerous pathways to prevent their expulsion or elimination from the host to ensure long-term survival. During infection, they target numerous host cells, including macrophages, to induce an alternatively activated phenotype, which aids elimination of infection, tissue repair, and wound healing. Multiple animal-based studies have demonstrated a significant reduction or complete reversal of disease by helminth infection, treatment with helminth products, or helminth-modulated macrophages in models of allergy, autoimmunity, and sepsis.

Modulation of specific and allergy-related immune responses by helminths.

Helminths are master regulators of host immune responses utilising complex mechanisms to dampen host protective Th2-type responses and favour long-term persistence. Such evasion mechanisms ensure mutual survival of both the parasite and the host. In this paper, we present recent findings on the cells that are targeted by helminths and the molecules and mechanisms that are induced during infection.
