Sex in Immune Cells and Parasitic Diseases — A Complex Relationship

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Epidemiological studies consistently show that many parasitic diseases affect males more frequently than females. These disparities are multifactorial, arising partly from gender‐specific behaviors that influence exposure risk and health‐seeking practices, especially in low‐ and middle‐income countries. Increasing evidence also highlights that

Mechanisms of Immune Evasion, Dissemination, and Persistence in Leishmania amazonensis Infection

Parasite Immunology, Volume 48, Issue 1, January 2026.
ABSTRACT Leishmania amazonensis is one of the etiological agents of cutaneous leishmaniasis in its localised form. Moreover, this parasite can cause more severe disease conditions, such as diffuse and disseminated cutaneous leishmaniasis. The development of more severe clinical manifestations is associated with the parasite's ability to establish a ...
