[Association of the 5HTTLPR/rs25531 Genetic Variant with Depression in a Cohort of Primary Care Patients].

Unlabelled: Serotonin plays a central role in mood regulation and the development of depressive disorders. The serotonin transporter, the primary regulator of serotonin levels, presents genetic variants that affect its functionality.

Aim: To study whether functional bi-allelic 5-HTTLPR or tri-allelic 5-HTTLPR/rs25531 polymorphisms in the serotonin transporter gene are associated with the diagnosis of depression.

Maca (Lepidium meyenii Walp.) inhibits HIV-1 infection through the activity of thiadiazole alkaloids in viral integration.

Ethnopharmacology Relevance: Lepidium meyenii Walp. (maca) has been traditionally used for centuries in the Central Andes region both as food and as medicine. In the last decades, its fertility enhancer properties have gained importance, with the majority of the scientific literature related to this topic.

Expansion of CD56CD16 NK Cell Subset and Increased Inhibitory KIRs in Hospitalized COVID-19 Patients.

Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection induces elevated levels of inflammatory cytokines, which are mainly produced by the innate response to the virus. The role of NK cells, which are potent producers of IFN-γ and cytotoxicity, has not been sufficiently studied in the setting of SARS-CoV-2 infection. We confirmed a different distribution of NK cell subsets in hospitalized COVID-19 patients despite their NK cell deficiency.
