Background: Intrinsic capacity (IC) is a concept related to functionality that reflects healthy aging. ATPase inhibitory factor 1 (IF1) is a multifaceted protein that regulates mitochondrial oxidative phosphorylation (OXPHOS), and may be involved in IC. The objective of this study is to investigate the association between plasma levels of IF1 and IC changes in community-dwelling older adults.

Article Synopsis
  • - Macrophages play a crucial role in HIV-1 infection and serve as significant viral reservoirs, particularly in various tissues where they are not easily infected by free virus.
  • - The study reveals that HIV-1 can efficiently infect macrophages through cell fusion with infected CD4+ T cells, highlighting a critical method of viral transmission in vivo.
  • - This fusion process varies based on the polarization state of the macrophages and is regulated by a specific adhesion structure and the CD81 tetraspanin, which influences cellular contractility during the infection.

Unlike other Flaviviruses, Zika virus (ZIKV) infection during the first trimester of pregnancy causes severe pregnancy outcomes including the devastating microcephaly and diseases associated with placental dysfunctions. We have previously reported that the maternal decidua basalis, the major maternal-fetal interface, serves as a replication platform enabling virus amplification before dissemination to the fetal compartment. However, the rate of congenital infection is quite low, suggesting the presence of a natural barrier against viral infection.

The human decidua basalis, main uterine mucosa during pregnancy, provides an ex vivo model for studying natural protection of macrophages against HIV-1 infection at the mucosal level. Beyond pregnancy, the decidua constitutes also a valuable tool to assess tissue-resident macrophage infection. Here, we provide a detailed protocol for decidual macrophage purification and tissue infection.
