Nitric oxide production by Peromyscus yucatanicus (Rodentia) infected with Leishmania (Leishmania) mexicana

Memorias do Instituto Oswaldo Cruz, 2013
Peromyscus yucatanicus (Rodentia: Cricetidae) is a primary reservoir of Leishmania (Leishmania) mexicana (Kinetoplastida: Trypanosomatidae). Nitric oxide (NO) generally plays a crucial role in the containment and elimination of Leishmania.

Gene editing and scalable functional genomic screening in Leishmania species using the CRISPR/Cas9 cytosine base editor toolbox LeishBASEedit

eLife, 2023
CRISPR/Cas9 gene editing has revolutionised loss-of-function experiments in Leishmania, the causative agent of leishmaniasis. As Leishmania lack a functional non-homologous DNA end joining pathway however, obtaining null mutants typically requires ...

The proinflammatory activity of recombinant serum amyloid A is not shared by the endogenous protein in the circulation.

, 2010
OBJECTIVE: Elevated serum levels of the acute-phase protein serum amyloid A (SAA) are a marker for active rheumatoid arthritis (RA), and SAA can also be found in the tissues of patients with active RA.

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

The FEBS Journal, Volume 293, Issue 6, Page 1754-1770, March 2026.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),

The Leishmania major BBSome subunit BBS1 is essential for parasite virulence in the mammalian host [PDF]

, 2013
Bardet–Biedl syndrome (BBS) is a human genetic disorder with a spectrum of symptoms caused by primary cilium dysfunction. The disease is caused by mutations in one of at least 17 identified genes, of which seven encode subunits of the BBSome, a protein ...

Sex‐Specific Factors Influencing HIV Infection

Immunological Reviews, Volume 338, Issue 1, March 2026.
ABSTRACT Immune responses are key in controlling viral infections such as HIV‐1, which remains a global challenge to public health. X/Y‐chromosome‐encoded genes and sex steroid hormones can modulate immune cells and drive distinct patterns of gene and protein expression involved in antiviral function, impacting sex‐dependent immune responses and ...

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
