with human immune systems helped scientists prove that HIV causes AIDS, says Irving Weissman of Stanford University, and implanting human tumors in mice has allowed scientists to identify the cells that cause several cancers.

the human immune system to fight disease.
In the curious, serpentine way that science works, it would make perfect sense for the mystery of one world of cells (those of
the human immune system) to be solved by those of another (the trillions of bacterial boarders that live within our bodies).
Behe (the author of Darwin's Black Box) once said also that
the human immune system is irreducibly complex.
Caused by a virus called HIV it has the capacity to attack and destroy
the human immune system, leaving the individual vulnerable to the infections that eventually cause death.
I've read (in Scientific American I believe) recent research suggesting that H Pylori helps regulate
the human immune system (for its own gain, of course, but ours too by suppressing auto - immune diseases).

the human immune system.
Because
the human immune system may not mature completely for several years, the constituents of human milk continue to support the host defense of the infant.
Vaccinate is essential to increase
the human immune system.
The stocks are helping the development of new countermeasures such as drugs, vaccines and diagnostics in case smallpox should reappear, and may also allow researchers to explore the impact of smallpox on
the human immune system, providing insights into other diseases such as AIDS.
The human immune system targets these particles for destruction based on their H and N sequences, and flu viruses constantly evolve the sequence of amino acids in these proteins to evade detection.
Dr Tomi Pastinen, senior author on the second study, from McGill University said: «We have created an expansive, high - resolution atlas of variations that deepens our understanding of the interplay between the genetic and epigenetic machinery that drives the three primary cells of
the human immune system.
The current test is only able to analyze part of
the human immune system, namely the B - cells but not the T - cells, which are needed as helper cells to fight the infection and whose activity indicates the presence of an infection.
The human immune system is adept at recognizing antigens it has met before: Antibodies snap onto the projecting viral proteins and prevent the organism from infecting other cells.
«Lacking this enzyme due to SAMHD1 gene mutations can activate
the human immune system and increase inflammation, and now we better understand the fundamental biological process behind that,» Wu said.
Based on our knowledge of the flu virus and
the human immune system, we can use computers to design the components of a vaccine that gives much broader and longer - lasting protection.»
In this respect, the current Helmholtz study opens the door to further research on the role of microRNA in terms of how
the human immune system reacts to environmental stressors.
One of Dozier's evolutionary computation projects uses
the human immune system to model a network security system.
Certainly one reason is that influenza viruses have a history of jumping from other animals to humans, which, when the trans - species virus is new to the human population, generally means that
human immune systems have no natural resistance.
Soon after, physicians approached Church about using CRISPR to alter the genomes of pigs so their organs would not be rejected by
the human immune system.
An unknown component of breast milk appears to kill HIV particles and virus - infected cells, as well as blocking HIV transmission in mice with
a human immune system.
One gene, she said, would shield its organs from attack by
the human immune system; another would revamp its coagulation system to reduce the risk of clots.
In this study, the Hiroshima University researchers developed an animal model using severely immunodeficient mice whose livers were partially populated with human cells, in order to reconstruct elements of
the human immune system.

the human immune system, was founded in Dublin in 2004 by three immunologists at Trinity College Dublin.
Coley, however, was the first to study and test the efficacy of what would come to be known as immunotherapy, coaxing
the human immune system to fight cancer.
And it results as a complication of catching strep, which evades
the human immune system by adapting its outer surface to resemble human biomolecules, a phenomenon called molecular mimicry.
Concerned that the immune systems of clean mice might not be good proxies for
the human immune system — no human is brought up in such clean conditions and fed such clean food — they housed lab mice with mice from a pet store.
