#Scientists discover the mechanism behind the innate immunological memory There can be no argument it is extremely important to understand how immunity works.

Better knowledge about immunity would help scientists to come up with new, more effective ways to prevent outbreaks of diseases.

However, at this moment science is needed lacking knowledge about human immunity. For example, for a long time it was believed that acquired immunity type of immunity mediated by T-and B-cellsad memory,

whereas innate immunityhich is mediated by macrophages and other types of cells that react to certain molecules typically associated with pathogensid not.

But now scientists know things are not so simple. This was not hard to figure out

as plants and insects have innate immunity only, but seem to have immunological memory. Furthermore, scientists observed that herpes virus infection increases the resistance against bacteria in vertebrates,

which suggests that innate immunity also has memory, even though researchers have struggled to understand the mechanism behind it.

However, now scientists from the RIKEN Molecular genetics Laboratory have revealed the mechanism underlying the memory of innate immunity.

It turns out there are epigenomic changes induced by pathogen infections mediated by a transcription factor called ATF7.

Although it seems to be complicated extremely phenomenon, in the future this discovery may help everyone, including those, who struggle to understand the mechanisms behind the memory of innate immunity.

At first, research team discovered that in ATF7 knockout mice, macrophages appear similar to wild-type macrophages that have been activated by exposure to molecules that occur commonly in infections.

Even before that scientists knew heat shock or psychological stress induced epigenomic changes were mediated by ATF7-related transcription factors.

After exposure to that stress, changes remained for a long duration of time. This made researchers think that pathogen infections could induce epigenomic changes in macrophages via ATF7.

Scientists found that ATF7 transcription factor simply binds itself to a group of innate immune genes and silences their expression

which makes cells less responsive to infections. Scientists managed to make ATF7 inactive, by using a molecule found in the outer membrane of Gram-negative bacteria,

called a lipopolysaccharidel. It made ATF7 phosphorylated and immune-related genes in mice models were silenced no longer.

First of all, it may increase our understanding of the ygiene hypothesis It is the concept saying that pathogen infection

and unhygienic environment during infancy reduces the risk of allergy later in life. ygiene hypothesisis used to explain why in more developed countries with better hygiene habits the incidence of allergies

and asthma is increasing. Now scientists say that since they can explain that the pathogen-induced epigenomic changes mediated by ATF7 maintain for a long period of time,

they have a better explanation about how the changes are induced. Secondly, these new findings may be very helpful developing vaccines with more effective adjuvants.

Adjuvants are used compounds in vaccines that activate innate immunity they are necessary ingredient of efficient vaccines.

For a long time scientists thought that the effect of adjuvant can be maintained a several days only. But this new research shows that it is not necessarily true.

which would make for much more effective vaccines. As much as human immune system still remains not completely clear for science

this new research provides better understanding about how our immune system remembers appropriate reactions to stress.

Knowing how to form these memories may hide the key to creating better, more effective and long-lasting vaccines a

#Team develops quick way to determine bacteria antibiotic resistance Bacteria ability to become resistant to antibiotics is a growing issue in health care:

Staphylococcus epidermis is increasingly emerging as a cause of multi-resistant hospital-acquired infections. The ability to quickly judge whether a bacteria is resistant to antibiotics could make a major difference in a patient's treatment.

Shannon Hilton and Paul Jones Staphylococcus epidermis is increasingly emerging as a cause of multi-resistant hospital-acquired infections.

Mark Hayes National summary data from the Centers for Disease Control and Prevention indicate that each year in the United states,

at least 2 million people acquire serious infections with antibiotic-resistant strains of bacteria. At least 23,000 people die as a direct result of these infections,

and many more die from related complications. It is not just humans that are threatened by this growing adaptation.

however, Staphylococcus epidermidis has emerged increasingly as a cause of multi-resistant hospital-acquired infections. Immunocompromised patients

indwelling medical devices, and surgically implanted prostheses provide suitable environments for Staphylococcus epidermidis to propagate and form biofilms.

#Researchers find biomarker for autism that may aid diagnostics By identifying a key signaling defect within a specific membrane structure in all cells, University of California,

they have found both a possible reliable biomarker for diagnosing certain forms of autism and a potential therapeutic target.

Dr. J. Jay Gargus, Ian Parker and colleagues at the UCI Center for Autism Research & Translation examined skin biopsies of patients with three very different genetic types

of the disorder (fragile X syndrome and tuberous sclerosis 1 and 2). They discovered that a cellular calcium signaling process involving the inositol trisphosphate receptor was altered very much.

This IP3R functional defect was located in the endoplasmic reticulum which is specialized among the membrane compartments in cells called organelles,

and possibly digestive and immune problems associated with autism. e believe this finding will be another arrow in the quiver for early and accurate diagnoses of autism spectrum disorders,

said Gargus, director of the Center for Autism Research & Translation and professor of pediatrics and physiology & biophysics. qually exciting,

Study results appear online in Translational Psychiatry, a Nature publication. Autism spectrum disorder is a range of complex neurodevelopmental disorders affecting 2 percent of U s. children.

The social and economic burden of ASD is enormous currently estimated at more than $66 billion per year in the U s. alone.

which impedes diagnosis and, ultimately, drug development. There simply may be too many targets, each with too small an effect.

According to Gargus, diseases of the organelles, such as the ER, are an emerging field in medicine,

with several well-recognized neurological ailments linked to two other ones, the mitochondria and lysosomes.

The IP3R controls the release of calcium from the ER. In the brain, calcium is used to communicate information within and between neurons

To see if IP3R function is altered across the autism spectrum, clinical researchers at The Center for Autism & Neurodevelopmental Disorders

which is affiliated with the Center for Autism Research & Translation are currently expanding the study

and have begun to examine children with and without typical ASD for the same signaling abnormalities.

In the area of drug discovery, scientists at the Center for Autism Research & Translation continue to probe the IP3R channel,

The brains of people who have autism show signs of hyperexcitability, which is seen also in epilepsy,

a disorder increasingly found to be associated with ASD. Cells from individuals who have depressed autism exhibit levels of calcium signaling

and this might explain why these patients experience this hyperexcitability. By restoring the release of calcium from the IP3R,

and senior author of a new paper on the work. his is the first of a series of ontrol knobsour lab is trying to create so doctors might have additional command over these cells once theye inside the body. ver the past two decades

, scientists pursuing cell therapy, one branch of the burgeoning field of cancer immunotherapy, have been refining cell-surface sensors known as chimeric antigen receptors, or CARS.

Once inserted into T cells, CARS prompt these cells to home in on particular proteins found primarily in tumors,

where they launch a series of cancer-killing immune responses. Dangers of CAR T cell Therapy CAR-equipped T cells have proven to be remarkably successful in the treatment of various forms of chemotherapy-resistant leukemia

But CAR T cell therapy can cause side effects so serious that they may require monitoring in an Intensive care unit several patients have died after receiving CAR T cells

or other forms of engineered T cells. cells are really powerful beasts, said Lim. nd they can be lethal when theye activated.

Wee needed a remote control system that retains the power of these engineered T cells, but allows us to communicate specifically with them

and manage them while theye in the body. ome scientists have grappled with these problems by developing uicide switchesthat kill off CAR T cells

when leukemia cells were implanted into mice. These cancer cells were powerfully and selectively eliminated by the Lim group new CAR T cells,

These combined control capabilities could be employed to manage the various side effects of CAR T therapy.

genetically engineered to carry CARS that target the patient tumor, then reinserted into the bloodstream to exert their effects.

in addition to attacking tumors directly, CAR T cells, like all T cells, release signaling molecules called cytokines, some

of which recruit additional T cells to fight the tumor. Sometimes normal cells express small amounts of a cancer-associated protein targeted by a CAR T cell.

Because CAR T cells placed in the bloodstream pass immediately through the heart and lungs, these tissues can be damaged before the CAR T cells reach their intended target elsewhere in the body.

In tumor lysis syndrome, the body is overwhelmed by toxic substances released when many tumor cells die in rapid succession.

which released cytokines summon numerous T cells to the tumor, then these newly arrived T cells release their own cytokines, and so on.

doctors may be able to precisely manage these side effects to meet individual patientsneeds. Proof of Principlelim stressed that the work reported in the new paper should be considered a proof of principle while useful for experiments,

While successful against blood cancers such as leukemia, CAR T cells have shown so far less efficacy against solid tumors that effect the colon, breast, prostrate, brain and other tissues.

The remote control strategy developed by Lim group may permit researchers to develop more powerful versions of CAR T cells that could attack these solid tumors,

so that the cells will respond to multiple characteristics that are distinctive to an individual patient tumor,
