The structural, functional, and therapeutic potential of metacaspases in fungi and protozoa

The FEBS Journal, EarlyView.
Metacaspases are Ca2+‐dependent cysteine proteases whose structural characteristics, particularly calcium binding and autocatalytic processing, govern their activation and biological functions. These enzymes differ among microorganisms and regulate their cell cycles, making them excellent targets for drug development.

Leishmania promastigotes evade interleukin 12 (IL-12) induction by macrophages and stimulate a broad range of cytokines from CD4+ T cells during initiation of infection. [PDF]

, 1994
Leishmania major are intramacrophage parasites whose eradication requires the induction of T helper 1 (Th1) effector cells capable of activating macrophages to a microbicidal state.

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

Targeting Aurora Kinases as Essential Cell‐Cycle Regulators to Deliver Multi‐Stage Antimalarials Against Plasmodium Falciparum

Angewandte Chemie, Volume 137, Issue 51, December 15, 2025.
In this study, we repurposed human Aurora kinase‐specific inhibitors to identify potential antimalarial agents. Two inhibitors, hesperadin and TAE684, exhibited sub‐micromolar activity across multiple parasite stages, with hesperadin demonstrating significant potency and selectivity by specifically targeting PfArk1.

Elevated baseline expression of seven virulence factor RNA transcripts in visceralizing species of : a preliminary quantitative PCR study

Therapeutic Advances in Infectious Disease, 2022
Introduction: Leishmaniasis is a neglected tropical disease that manifests as three major disease phenotypes: cutaneous, mucocutaneous, and visceral. In this preliminary study, we quantified virulence factor (VF) RNA transcript expression in Leishmania ...

Real-time imaging of Leishmania mexicana-infected early phagosomes: a study using primary macrophages generated from green fluorescent protein-Rab5 transgenic mice [PDF]

, 2009
The small GTPase Rab5 is a key regulator of endosome/phagosome maturation and in intravesicular infections marks a phagosome stage at which decisions over pathogen replication or destruction are integrated.

Artificial intelligence‐powered microscopy: Transforming the landscape of parasitology

Journal of Microscopy, EarlyView.
Abstract Microscopy and image analysis play a vital role in parasitology research; they are critical for identifying parasitic organisms and elucidating their complex life cycles. Despite major advancements in imaging and analysis, several challenges remain. These include the integration of interdisciplinary data; information derived from various model

Early suppression of lymphoproliferative response in dogs with natural infection by Leishmania infantum. [PDF]

, 1999
Dogs are the domestic reservoirs of zoonotic visceral leishmaniasis caused by Leishmania infantum. Early detection of canine infections evolving to clinically patent disease may be important to leishmaniasis control.
