The hippocampus is a heterogenous structure that exhibits functional segregation along its longitudinal axis. We recently showed that in male mice, microglia, the brain's resident immune cells, differ between the dorsal (DH) and ventral (VH) hippocampus, impacting long-term potentiation (LTP) mainly through the CX3CL1-CX3CR1 signaling. Here, we assessed the specific features of the hippocampal poles in female mice, demonstrating a similar LTP amplitude in VH and DH in both control and Cx3cr1 knock-out mice.

Article Synopsis
  • * A new community care model was developed, allowing for simplified HCV screening, testing, and treatment via telemedicine across 21 centers, leading to increased patient participation and improved management of HCV cases.
  • * Results from April 2021 to April 2023 showed that a significant portion of participants successfully engaged with the care model, resulting in a high rate of successful treatments and minimal reinfections, highlighting the effectiveness of decentralizing healthcare for PWUD.

CombiVacS study has demonstrated a strong immune response of the heterologous ChAdOx1-S/BNT162b2 vaccine combination. The primary outcomes of the study were to assess the humoral immune response against SARS-CoV-2, 28 days after a third dose of a mRNA vaccine, in subjects that received a previous prime-boost scheme with ChAdOx1-S/BNT162b2. Secondary outcomes extended the study to 3 and 6 months.

Early detection of disseminating vancomycin-resistant (VREfm) in ICU wards is crucial for outbreak identification and the implementation of prompt infection control measures. Genotypic methods like pulsed-field gel electrophoresis (PFGE) and whole-genome sequencing (WGS) are costly and time-consuming, hindering rapid response due to batch dependency. Fourier-transform infrared spectroscopy (FT-IR) offers the potential for real-time outbreak detection and reliable strain typing.

Background: The emergence of new SARS-CoV-2 variants and the waning of immunity raise concerns about vaccine effectiveness and protection against COVID-19. While antibody response has been shown to correlate with the risk of infection with the original variant and earlier variants of concern, the effectiveness of antibody-mediated protection against Omicron and the factors associated with protection remain uncertain.

Methods: We evaluated antibody responses to SARS-CoV-2 spike (S) and nucleocapsid (N) antigens from Wuhan and variants of concern by Luminex and their role in preventing breakthrough infections 1 year after a third dose of mRNA vaccination, in a cohort of health care workers followed since the pandemic onset in Spain (N = 393).
