Annexin A1 improves immune responses and control of tissue parasitism during Leishmania amazonensis infection in BALB/c mice.

Leishmaniases, a group of diseases caused by the species of the protozoan parasite Leishmania, remains a significant public health concern worldwide. Host immune responses play a crucial role in the outcome of Leishmania infections, and several mediators that regulate inflammatory responses are potential targets for therapeutic approaches. Annexin A1 (AnxA1), an endogenous protein endowed with anti-inflammatory and pro-resolving properties, has emerged as a potential player.

Mapping Alterations Induced by Long-Term Axenic Cultivation of Promastigotes With a Multiplatform Metabolomic Fingerprint Approach.

Leishmaniases are widespread neglected diseases with an incidence of 1.6 million new cases and 40 thousand deaths per year. parasites may show distinct, species-specific patterns of virulence that lead to different clinical manifestations.

Methotrexate Locally Released from Poly(e-Caprolactone) Implants: Inhibition of the Inflammatory Angiogenesis Response in a Murine Sponge Model and the Absence of Systemic Toxicity.

In this study, the methotrexate (MTX) was incorporated into the poly(e-caprolactone) (PCL) to design implants (MTX PCL implants) aiming the local treatment of inflammatory angiogenesis diseases without causing systemic side effects. Sponges were inserted into the subcutaneous tissue of mice as a framework for fibrovascular tissue growth. After 4days, MTX PCL implants were also introduced, and anti-inflammatory, antiangiogenic, and antifibrogenic activities of the MTX were determined.
