Astrocyte Apoptosis and HIV Replication Are Modulated in Host Cells Coinfected with Trypanosoma cruzi [PDF]

open access: yes, 2017
The protozoan Trypanosoma cruzi is the etiological agent of Chagas disease. In immunosuppressed individuals, as it occurs in the coinfection with human immunodeficiency virus (HIV), the central nervous system may be affected. In this regard, reactivation

Ceramide is a Mediator of Apoptosis in Retina Photoreceptors [PDF]

open access: yes, 2006
PURPOSE. The precise mechanisms involved in photoreceptor apoptosis are still unclear. We here investigated the role of ceramide, a sphingolipid precursor that induces apoptosis upon cellular stress, in activating this death in photoreceptors.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Structural insights into glycan recognition by plant immune receptors: a comparative perspective with animal innate immune systems

open access: yesThe Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Pattern recognition receptors (PRRs) function across diverse eukaryotic organisms as a powerful surveillance system to perceive danger signals and to trigger specific adaptive responses. This complex receptor network constitutes the first layer of perception of the innate immune system of plants and mammals.
