New method to identify active tuberculosis in patients

Active tuberculosis can be rapidly identified in patients with negative sputum tests by a new method, according to European researchers. Active tuberculosis (TB) is the seventh-leading cause of death worldwide, and while the diagnosis of active TB can be rapidly established when the bacteria can be identified on sputum microscopy, in about half of all cases, the TB bacterium cannot be detected, making another diagnostic option critical in efforts to control the spread of TB.

Tregs to set the pace of recovery after serious lung injury

After more than 50 experiments in mice, medical scientists at Johns Hopkins have mapped out the basic steps taken by a particular set of white blood cells in setting the pace of recovery after serious lung injury.

Investigative drug hampers the survival of non-Hodgkin lymphoma cells

An investigative drug deprived non-Hodgkin lymphoma cells of their ability to survive too long and multiply too fast, according to an early study published recently in the journal Experimental Hematology.

Importance of residual thymopoiesis in aged adults

Doctor Manuel Leal is managing the Experimental Immune Virology Laboratory (in Virgen del Rocío University Hospital and Instituto de Biomedicina de Sevilla (IBIS), where clinic and basic science researchers work) where he leads a project to establish the functional nature of the thymus gland in adults. So far, it has been proven that this gland keeps on producing lymphocytes in the old age (Ferrando-Martínez et al. AGE, in press), which is a novelty because until very recently it was considered that this organ lost its immune capacity after the puberty.

Viral polymerase may provide a new therapeutic target for host-adapted avian influenza

Current research suggests that viral polymerase may provide a new therapeutic target for host-adapted avian influenza. The related report by Gabriel et al, "Spread of Infection and Lymphocyte Depletion in Mice Depends on Polymerase of Influenza Virus" appears in the September 2009 issue of the American Journal of Pathology.

Scientists find key to strengthening immune response to chronic infection

A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as some cancers, such as melanoma.

Simple blood test detects molecular marker of aging in humans

In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is a tumor suppressor protein, cancer researchers are interested in its role in cellular aging and cancer prevention.

Discovery of DNA mutation that occurs at beginning point of T-cell lymphoma

Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a key mechanism that causes chromosomes within blood cells to break - an occurrence that marks the first step in the development of human lymphoma.

If started early, HIV treatment reduces death rates toward background levels in African countries

Mortality rates of people starting HIV treatment in four African countries approach those of the general population over time, provided that treatment is started before the immune system has been severely damaged, according to research published this week in the open-access journal PLoS Medicine.

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates, and are capable of becoming only cells of a particular type of tissue.

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates and are capable of becoming only cells of a particular type of tissue. So how do these tissue-specific stem cells restrict their fate?

Microfluidic devices capture and analyze single cancer cells

One of the grand goals in nanotechnology is to develop a single microfluidic device that integrates all of the components needed to perform polymerase chain reaction (PCR)-based nucleic acid analyses. Experts predict that such a device would enable researchers to develop rapid assays for cancer and other life-threatening diseases while a patient is in the doctor's office.

Discovery of new regulatory circuit controlling immune cell production in mice

Using a mouse model, researchers have shown that elevated levels of a small protein known as interleukin 7 (IL-7) plays a central role in regulating the production of a type of white blood cell that is required for effective immune responses.
