The role of regulatory CD4+CD25+ T cell subset in host homeostasis during protozoan infection

Human diseases caused by protozoan parasites are renowned for their high rates of morbidity and mortality worldwide. Some examples include African trypanosomiasis or sleeping sickness, American trypanosomiasis or Chagas disease, leishmaniases, malaria and babesiosis. These infections tend to follow a chronic rather than an acute course with lifelong persistence of parasites. Regulatory T cells (Treg), in […]

The battle between Leishmania and the host immune system at a glance

Leishmaniasis is a neglected parasitic disease whose diverse clinical manifestations are dependent on the interrelations between intrinsic and extrinsic factors. The infecting species of Leishmania, the parasite’s ability to evade mammal immune response and the host genetic background seems to pre-determine the degree of resistance and sensitivity to infection, regulating the disease outcome. The introduction […]

Cattle Specific Immune Mechanisms used against the Protozoan Theileria annulata

Theileria annulata, the causative agent of tropical theileriosis, is an intracellular protozoan parasite transmitted by ticks of the genus Hyalomma. This tick-borne disease (TBD) exerts a high impact on livestock production in many developing tropical and subtropical countries. With an intricate life cycle and wide distribution around the world, many advances were made to restrict […]

Anopheles gambiae and A. stephensi Immune Response during Plasmodium berghei Infection Uncovered by Sialotranscriptomic Analysis

Malaria is caused by parasites of the genus Plasmodium that are transmitted through the bite of female mosquitoes of the genus Anopheles. Responsible for high mobility and mortality rates around the world, this protozoan disease is most common in the tropical and sub-tropical regions. Herein, using a pure transcriptomic data analysis approach on mosquito salivary […]
