Strengthen Immune System
following are articles about research on factors that either
weaken or strengthen the immune system:
Article 17: Sudden
Removal Of Fat Impairs Immunity Function In Rodents, Biologists
Find This study is the first to show that even a moderate
loss of fat leads to decreased amounts of infection-fighting
IgG antibodies. The study has implications for people concerned
about how to boost their immune system...
Article 16: Bacterial
Viruses Make Cheap Easy Vaccines Genetically altered bacterial
viruses appear to be more effective than naked DNA in eliciting
an immunity response and could be a new strategy for a next
generation of vaccines that will boost the immune system...
Article 15: Scientists
Discover How To Grow Cells That Suppress Immunity Responses
Normally we are looking to build up the immune system. But
sometimes we want to suppress some immunity reactions. Researchers
have discovered how to grow T-regulatory cells type 1 (Tr1)
which are thought to turn off unnecessary immunity reactions...
Article 14: New Role
For Immunity Player May Help Improve Cancer Vaccines Researchers
have discovered that a molecule best known for its anti-microbial
properties also has the ability to activate key cells in the immune
system. This may lead to new cancer vaccines and strategies to
build up the immune system..
Article 13: New
Approach To Replacing Immunity Cells Shrink Tumors In Patients
With Melanoma The
study demonstrates that immune response cells, activated in
the laboratory against patients' tumors and then administered
to those patients, can attack cancer cells in the body. What
an awesome way to boost the immune system...
Article 12: Researchers
Identify Protein That Regulates Killer Cells Researchers have
identified a protein that plays a critical role in the regulation
of "natural killers cells" in our immunity battle against
foreign and diseased cells. This research is a small part of the
larger search for how to improve the immune system...
Article 11: White
Blood Cells Are Much More Active And Dynamic White blood cells
are much more active and dynamic than previously assumed and show
complex behaviors for responding to foreign bodies. The study
gives new insight into the tactics used by T- and B-cells to fight
disease and has implications for bolster the immune system...
Article 10: Researchers
Identify A Key "Brake" Of The Immunity Response
Sometimes physicians want to be able to turn off the immunity
response, such as during bone marrow or organ transplants to prevent
the host from rejecting the donor tissue. On the other hand, doctors
would like to build up the immune system response against malignant
cells and HIV-infected cells to help fight cancer and AIDS...
Article 9: Blood Stem
Cells Carry Targeted Genes In a bold new move to strengthen
the immune system, researchers have genetically altered human
blood stem cells to selectively activate genes in developing immunity
Article 8: Signals
From Nervous System Influence Immunity, Study Shows In
a discovery that demonstrates a clear link between the mind and
body at a molecular level, scientists have shown that a chemical
signal which normally allows nerve cells to communicate with each
other can also re-direct actions of the immune system. We can
utilize this information to boost the immune system...
Article 7: University
Of Pittsburgh Researchers Define Precursors To Cells That Control
The Immunity Response Precursors
of epidermal Langerhans cells (LCs) reside in the skin and play
a key role in the initiation and regulation of the immunity response
throughout the body. Researchers may now be able to use these
cells to build up the immune system response...
Article 6: Researchers
Identify Pathogen-Specific Gene Response In Human Immunity Cells
Using DNA microarray technology, researchers at the Whitehead
Institute for Biomedical Research have discovered that a type
of human cell, known as a dendritic cell, initiates an immunity
response that is tailor-made for specific infectious organisms.
The researchers found that dendritic cells turn on different sets
of genes, or a signature pattern of gene response, depending on
whether the organism is a bacteria, virus, or fungus....
Article 5: Natural
Immunity Response Reduces Nerve Damage; May Lead To Improved
Treatment For Spinal Cord Injury Scientists
show for the first time that damage to the central nervous
system causes the body to mount an immunity reaction against
itself that actually protects neurons from further damage.
This may lead to insights into how to build up the immune
system of those with spinal cord injury...
Article 4: Research
Holds Hope For Understanding Recurrent Miscarriages, Helping
Transplant And Cancer Patients A
mother's immune system may attack a fetus from multiple fronts,
by sending in killer T-cells, by producing antibodies that
target fetal cells or by coating cells with a destructive,
soluble blood factor called complement. Hopefully we can understand
how to make the immune system stronger in all patients and
avoid attacks where they are not wanted...
Article 3: Immunity Proteins Play
Role In Brain Development And Remodeling; Discovery Suggests New
Theory For Dyslexia, Parkinson's Disease And Multiple Sclerosis
Two immunity proteins found in the brains of mice help the brain
develop and may play key roles in triggering developmental disorders
like dyslexia and neurodegenerative disorders like Parkinson's
Disease, according to a Harvard Medical School study...
Of Iowa Researchers Investigate Regulation Of Immunity Memory
a person's immune system successfully fights off an infection,
not only does that person recover, but they also acquire immunity
against re-infection by that same pathogen. The ability of
the body to remember pathogens it has already defeated, and
to respond rapidly and effectively to them during future exposures,
is the basis of vaccination strategies...
Immune System: Promiscuity May Be One Way Evolution Has Found
To Do This, A Study Suggests What
a strange way to build immunity - this study indicates that
the evolution of immunity in a species may be directly linked
to the sexual activity of that species. A comparative analysis
of 41 primate species demonstrates that the most promiscuous
species have naturally higher white blood cell (WBC) counts
-- the first line of defense against infectious disease --
than more monogamous species...
