The central nervous system (CNS) is extremely resistant to infection by bacterial pathogens due to a combination of protective effects of its bony structures (skull and vertebral column), the meninges, and the blood-brain barrier. (medscape.com)
The researchers report in the journal Nature Communications the unexpected finding that the common yeast Candida albicans, a type of fungus, can cross the blood-brain barrier and trigger an inflammatory response that results in the formation of granuloma-type structures and temporary mild memory impairments in mice. (bcm.edu)
They injected C. albicans into the blood stream of mice and were surprised to discover that the yeast can cross the blood-brain barrier, a robust protective mechanism the brain employs to exclude all kinds of large and small molecules, as well as a number of microorganisms that can potentially damage the brain. (bcm.edu)
The work builds on the idea that as the blood-brain barrier gets weak with age, it can't keep infections out. (labroots.com)
They actively participate in immune responses, as well as form functional barriers, such as blood-brain barrier (BBB), which restrict the entry of pathogens and inflammatory mediators into the CNS. (techscience.com)
Inspired by brain-invading bacteria, researchers have created nanocapsules that covertly shuttle drugs across the blood-brain barrier. (advancedsciencenews.com)

There are, unfortunately, few therapeutic options, with the blood-brain barrier being one of the major challenges in treating these types of tumors. (advancedsciencenews.com)
Radiotherapy is often associated with cognitive impairment and intracranial relapse [and] systemic medical therapies are also impacted by the blood-brain barrier, resistance, and other drug-related problems. (advancedsciencenews.com)
It is urgently needed to develop systemic medical therapies that could overcome the issues of the blood-brain barrier and low tumor-targeting because pharmacotherapy is involved in relatively low physical damage to the body compared with other types of therapies. (advancedsciencenews.com)
To make better therapeutic options available to patients with brain metastasis, Han and his team developed and tested nanocapsules loaded with drugs that can safely cross the blood-brain barrier. (advancedsciencenews.com)
In a recent study published in Small , the team led by Han coated drug-loaded nanocapsules with biological components taken from bacterial membranes that work like an entrance ticket through the blood-brain barrier. (advancedsciencenews.com)
Taking advantage of this known mechanism, Han and his team coated nanocapsules composed of a biocompatible and biodegradable polymer called poly(lactic-co-glycolic acid) with E. Coli outer membrane proteins known to interact with GRP94 in the blood-brain barrier. (advancedsciencenews.com)
Han and the team therefore decided to test a theory: by delivering a key molecule inside the nanocapsule called embelin, could they not only get an essential therapy past the blood-brain barrier, but also stop this deadly defense mechanism in cancer cells, enhancing the anti-tumor effects of the drug.

Many studies have reported on complications that can occur as an immediate result of a serious COVID infection, such as heart failure or the worsening of existing diabetes . (yahoo.com)
While these immediate complications remain a priority, we also know the virus can affect people's health many months after initial infection. (yahoo.com)
Meanwhile, a UK preprint (a study yet to be peer-reviewed) reported cardiovascular complications were elevated for up to 49 weeks after infection. (yahoo.com)
However, long COVID may overlap with other complications of acute COVID-19 illness, making it hard to define because the spectrum of COVID-19 severity varies, it can be hard to differentiate between the long term effects specific to SARS-CoV-2 infection from those that occur in other illnesses. (cdc.gov)

An assistant professor of biology at Arcadia University, he conducts research on understanding how the immune system eliminates viral infections of the mammalian central nervous system (CNS), while sparing this essential organ system. (arcadia.edu)
Since viruses often commandeer the cellular machinery during infection to construct more viruses, the immune system often eradicates viral infections by targeting and killing infected cells in order to eliminate the 'virus factories. (arcadia.edu)
Therefore," he says, "viral infections of the CNS present a particular challenge to the immune system: since neurons of the CNS are generally non-renewable, classical antiviral strategies involving the killing of infected cells would be of great detriment to the host. (arcadia.edu)
Scientists have found that the condition can cause noticeable changes to the body's immune system and has an effect on the brain similar to chronic fatigue. (sciencealert.com)
