Lutzomyia longipalpis Lutz & Neiva, 1912 (Diptera, Psychodidae), is the primary vector of Leishmania infantum Nicole, 1908, the etiological agent of American visceral leishmaniasis. During their development, sandfly larvae pass through four instars, consuming soil particles enriched with microorganisms and decomposing organic material. In numerous insect species, the intestinal epithelium not only secretes digestive enzymes and absorbs digested nutrients but also carries out additional functions, such as regulating luminal pH and facilitating the absorption or secretion of ions and water.

Leishmania spp. infections lead to a notable alteration in macrophage metabolism, whereby infected cells display heightened energy metabolism that is linked to the integrity of host mitochondria.

- Long COVID, also known as post-acute sequelae of COVID-19 (PASC), involves lasting symptoms affecting various body systems, particularly the central nervous system (CNS) which includes issues like fatigue, brain fog, and cognitive deficits.
- The review highlights potential mechanisms for neuro-PASC, suggesting that vascular dysfunction and disruption of the blood-brain barrier (BBB) could be key contributors to these neurological symptoms.
- It further investigates the role of the COVID-19 spike protein interacting with brain cell receptors, which may play a significant part in the pathophysiology of long COVID symptoms.
Statins as potential disease-modifying therapy of Parkinson's disease: a systematic review and meta-analysis with trial sequential analysis.
Acta Neurol Belg
December 2024
Background: Recent evidence indicates that statins have anti-inflammatory and antioxidant effects, leading to several investigations of whether statins have a neuroprotective effect and may benefit patients with Parkinson's disease (PD). However, the potential mechanisms of this class of medications as modifiers of the course of PD in already diagnosed patients is still unclear.
Objectives: To assess the effectiveness of statins as modifiers of established PD.
