Introduction: While the general immune response to Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) is well-understood, the long-term effects of Human Immunodeficiency Virus-1/Severe Acute Respiratory Syndrome-Coronavirus-2 (HIV-1/SARS-CoV-2) co-infection on the immune system remain unclear. This study investigates the immune response in people with HIV-1 (PWH) co-infected with SARS-CoV-2 to understand its long-term health consequences.
Methods: A retrospective longitudinal study of PWH with suppressed viral load and SARS-CoV-2 infection was conducted.
Article Synopsis
- Biofilms are communities of bacteria that attach to surfaces and are held together by a matrix, but how this matrix interacts with the cells is not fully understood.
- The study focuses on *Vibrio cholerae*, the bacteria responsible for cholera, and reveals that the main matrix component, Vibrio polysaccharide (VPS), does not attract the cells, but a protein called Bap1 helps link the cells together.
- As biofilms age, changes in VPS levels and a process called surface trimming lead to a shift in cell-matrix interactions from attractive to repulsive, promoting cell dispersal and potentially enriching our understanding of biofilm growth dynamics in other microorganisms.
Background: The alcohol industry uses many of the tobacco industry's strategies to influence policy-making, yet unlike the Framework Convention on Tobacco Control, there is no intergovernmental guidance on protecting policies from alcohol industry influence. Systematic assessment of alcohol industry penetration and government safeguards is also lacking. Here, we aimed to identify the nature and extent of industry penetration in a cross-section of jurisdictions.
