In animal studies, exosomes secreted
by immune cells during environmental enrichment caused cells in the brain to start myelin repair.

And a new analysis of the STEP trial, published last November in Proceedings of the National Academy of Sciences USA, provides a warning that the very vectors (adenoviruses, which are also employed in other vaccine development work) used to distribute the inactive HIV strains can actually make the
immune system more vulnerable to infection
by recruiting susceptible T
cells to mucous membranes, where they are more likely to be infected
during sexual activity.
But
during pregnancy, the fetus is protected from the mother's
immune system
by the placenta, which has specialized
cells — called trophoblasts — that can burrow into the mother's body without exciting an attack
by the
immune system.
By studying infected cells grown in a laboratory, the team found that a large number of CMV's genes help it hide from the immune system by allowing it to destroy many of the proteins produced by the body during virus infection and preventing them from activating immune cells to destroy the viru

And a new analysis of the stopped STEP trial, published online Monday in Proceedings in the National Academy of Sciences, provides a warning that the very vectors (adenoviruses, which are also employed in other vaccine development) used to distribute the inactive HIV strains can actually prime the
immune system to be infected
by recruiting susceptible T
cells to mucous membranes, where they are more likely to be infected
during sexual activity.
A certain cytokine, or small protein that helps
cells communicate
during immune responses, can control whether
immune cells promote or suppress inflammatory bowel disease, a finding that could lead to new treatments, according to a study led
by Georgia State University.
To prevent collateral damage to precious nerve
cells during immune skirmishes, the brain and spinal cord are tightly sealed off from the rest of the body
by the blood - brain barrier.
The studies, conducted separately on the East and West coasts of the United States, attempt to make the
immune system resistant to HIV
by crippling a receptor, known as CCR5, on T
cells that the virus uses
during the infection process.
Researchers at St. Jude Children's Research Hospital have discovered the mechanism
by which
immune cells called regulatory T
cells keep themselves intact and functional
during their demanding task of holding the
immune system in check.
Control of virus - specific CD8 + T -
cell exhaustion and
immune - mediated pathology
by E3 ubiquitin ligase Cbl - b
during chronic viral infection.
Kraig and his team, which includes Aya Pusic and Kae Pusic, PhD, discovered that dendritic
cells, professional antigen presenting
cells of the
immune system, can be stimulated
by factors released
during environmental enrichment to produce exosomes containing microRNAs that improve brain health.
However, the exact cytoskeletal strategy that the
cell uses to cross the physical BM barrier depends on the physiological context and the physical environment, as observed
by examining actin structures in invading cancer and
immune cells, and in
cells that invade
during developmental processes such as angiogenesis and anchor
cell invasion in Caenorhabditis elegans.
People with heart disease have high levels of CRP in their blood because it's released
by cells during inflammation, the
immune system's attempt to defend against disease or infection.
