Controlling and analyzing neural circuits in vivo would be facilitated by a technology for delivery of viruses and other reagents to desired 3-dimensional sets of brain regions. We demonstrate customized fluidic injector array fabrication, and delivery of virally-encoded optical sensitizers, enabling optical manipulation of complex brain circuits.

Reservoir of Infection
0 Views •
2026
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...

Veins as Blood Reservoirs

2024
Veins, while chiefly responsible for circulating blood back to the heart, also function as storage vessels for blood. They house approximately 64 percent of the body's total blood volume, a feat made possible by their high capacitance—the inherent ability to expand and accommodate large volumes of blood, even under low pressure. The large diameter and thin walls of veins augment their distensibility, significantly more so than arteries, due to their classification as capacitance vessels. When...

Here, we describe a simple method of intracerebroventricular and intravascular injection of viral particles or fluorescent microbeads into the neonatal mouse brain. The localization pattern of the virus and nanoparticles could be detected by microscopic evaluation or by in situ hybridization.
FAQs
Two protective features of the central nervous system complicate clearance: the blood-brain barrier can limit drug penetration, while restricted immune surveillance may reduce access by immune responses. Together, these conditions can allow infected cells or viral genetic material to persist even when treatment suppresses infection elsewhere. This makes the brain a distinct compartment for studying persistence.
Microglia matter because they are long-lived cells within the central nervous system and can harbor proviral DNA. Their longevity gives infected material a cellular setting in which it may remain over time, rather than being removed through rapid cell turnover. Examining microglia therefore helps explain why brain-associated persistence remains relevant to HIV cure research.
Latency changes the reservoir from an actively producing target into a less visible form of persistence. Proviral DNA can remain in cells while virus production stays low, reducing opportunities for immune responses or treatment to eliminate it. If this latent material later supports renewed production, it may contribute to viral rebound, so measuring DNA and ongoing production addresses different aspects of persistence.
Mapping should account for both the location of infected cells and the form of viral persistence present there. Some reservoir evidence may appear as proviral DNA, whereas other evidence may involve low-level virus production. Separating these states can clarify whether a tissue contains latent genetic material, ongoing production, or both, improving interpretation of persistence studies.
Brain reservoir studies support HIV cure strategies, antiviral drug development, and analysis of persistent infection in the central nervous system. Identifying where persistence occurs and whether it involves proviral DNA or low-level production can show why treatment does not fully clear infection. This information supports efforts to address reservoirs that remain protected from complete clearance.
The neurological concern is not limited to viral persistence itself. Brain-associated reservoirs may contribute to chronic neuroinflammation and neurological injury, linking cellular infection to damage in nervous tissue. Studying this relationship helps neuroscience examine how persistent infection affects the central nervous system and why eliminating or controlling reservoirs may matter for neurological outcomes.
