Resistant HIV quickly hides in infants' cells
...ut levels of resistant virus declined over time to undetectable
levels. In the current study, however, researchers found these resistant viruses quickly took up residence in inactive T cells, from where they could later launch an attack that NNRTIs could not stop. The news was not all bad: a different class of a...

until the disease has progressed to the point where survival is almost nil. Moreover, these cells appear to be highly sensitive to the tumor-promoting properties of TGFb and thereby manifest a more aggressive behavior. "With accurate animal models...
Newly identified biomarker detects and regulates spread of brain tumors
... absent in the central nervous system (CNS) and is undetectable
in cerebral spinal fluid (CSF), unless malignant astrocytomas--the most common form of intracranial tumors--are present in the CNS. The CSF is a liquid that bathes the brain and acts as a reservoir, which can be sampled for analysis of proteins secre...

...rapeutic levels. Thus, although HAART may achieve undetectable
virus levels in the blood, virus replication in the testis may permit continued spread of the virus. Finally, with HIV infection continuing to rise, the development of anti-retroviral therapy that effectively targets all sources of HIV, including...

CHAVI announces international search for genes affecting HIV response
...ome people naturally hold the virus down to almost undetectable
levels while others lose control of it quickly." The newly organized group, called EuroCHAVI, will recruit 600 patients from nine cohorts. "This will be is the largest cohort assembled for large-scale analysis of genetic differences among HIV-infect...
Protein found to control tumor growth in certain breast cancers
...minished rapidly in these mice, becoming virtually undetectable
by the end of the experiment. In MCF-7 cells where Nod1 was absent, the tumors flourished. In addition, there was an increased sensitivity to estrogen-induced cell proliferation and a failure to undergo Nod1-dependent apoptosis in vitro. Takin...
Chemical warfare agent detection technology used to treat lung disease

tumour metabolising inside a human lung simply by asking a patient to breathe into a device like this. For now our aim to use the microDMx sensor to develop better instruments which will improve patient care and treatment. "The potential is such tha...
The reason why antiviral therapy can't annihilate HIV infection, and what to do about it

levels of HIV in their plasma. Their data also suggest that latently infected, resting CD4+ T cells may become reactivated, most likely as a result of normal immunologic responses to various antigens and cytokines. In turn, virions released during ...
