Study demonstrates that HIV infection in the brain can be established, maintained by T cells

A new study by University of North Carolina School of Medicine researchers has found that T cells, a type of white blood cell and an essential part of the immune system, are sufficient by themselves to establish and maintain an HIV infection in the brain.

Novel PET imaging shows promise for noninvasively detecting inflammation in people with IBD

A novel positron emission tomography imaging method shows promise for noninvasively pinpointing sites of inflammation in people with inflammatory bowel disease, which includes ulcerative colitis and Crohn's disease.

Scientists report involvement of estrogen hormone receptor in autoimmune diseases

Women are more prone to the development of autoimmune diseases. The female hormone estrogen is likely to affect the immune system.

New study unravels secrets of HIV's persistence

Thanks to advances in the development of anti-retroviral therapy (ART), patients with HIV are living longer than ever before. And yet, even in patients on very effective, long-term ART, HIV persists, requiring patients to take antiviral medication life-long.

Nuclear pore complexes are critical for survival of circulating T cells, study shows

Nuclear pore complexes in the nuclear membrane not only control the transport of molecules into and out of the nucleus- they play an essential role in the survival of T cells.

Research findings challenge feasibility of 'shock and kill' approach to cure HIV

Researchers have provided new insight into the cellular processes behind the 'shock and kill' approach to curing HIV, which they say challenges the effectiveness of the treatment.

Precancerous colon polyps in Lynch syndrome patients display immune activation

Colon polyps from patients with Lynch syndrome, a hereditary condition that raises colorectal cancer risk, display immune system activation well before cancer development, according to research from The University of Texas MD Anderson Cancer Center.

Researchers get one step closer to creating peptide vaccine against atherosclerosis

In the disease atherosclerosis, cholesterol-containing plaques form in vessel walls, causing arteries to narrow and greatly increasing the risk of heart attack and stroke.

Researchers discover Tfh cell dysfunction in HIV-infected patients

A team of chemical and biomedical engineers from the Cockrell School of Engineering at The University of Texas at Austin, in collaboration with researchers from the University of Pennsylvania, have discovered that HIV-infected patients experience a dysfunction in a certain type of immune cell: the follicular helper T (Tfh) cell.

Study uncovers mechanism causing chronic GVHD after bone marrow transplant

Allogeneic bone marrow transplant (BMT) is an essential treatment to cure patients with blood cancers such as leukemia. In patients who have undergone chemotherapy and radiation, a small number of cancer cells can remain in the bloodstream and allow the malignancy to recur.

Specific immune cells may help slow progression of ALS, research shows

New research into Amyotrophic Lateral Sclerosis (ALS) - also known as motor neuron disease - shows that specific immune cells may help slow progression of the disease, an important step towards developing new therapies to treat patients.

Gut microbiome may promote pancreatic cancer by inducing immune suppression

Bacterial load was significantly higher in pancreatic tumor samples from patients with pancreatic ductal adenocarcinoma compared with pancreatic tissue from normal individuals, and in studies using mice, eliminating certain "bad" bacteria slowed the growth of pancreatic cancer, reversed immune suppression, and upregulated the immune checkpoint protein PD1.

New study examines origin of cryptococcosis within the central nervous system

A particular fungal infection is responsible for more than 220,000 cases of cryptococcosis worldwide each year in people with HIV and AIDS, with nearly 181,000 of those resulting in death.

One-month antibiotic regimen to prevent TB as safe, effective as nine-month therapy for HIV patients

A one-month antibiotic regimen to prevent active tuberculosis (TB) disease was at least as safe and effective as the standard nine-month therapy for people living with HIV, according to the results of a large international clinical trial.

Antibiotic use may affect efficacy of cancer immunotherapies

Antibiotic use is known to have a near-immediate impact on our gut microbiota and long-term use may leave us drug-resistant and vulnerable to infection.

Study unravels novel cellular and molecular pathway that regulates innate, adaptive immunity

Researchers at Brigham and Women's Hospital have discovered a new cellular and molecular pathway that regulates CD4+ T cell response--a finding that may lead to new ways to treat diseases that result from alterations in these cells.

Scientists discover the genetic cause of immune disorders

Scientists from the Cincinnati Children’s have successfully identified a gene mutation that affects T cell function and promotes immune disorders.

Scientists discover how gene mutation affects T cell function to promote immune disorders

Scientists discovered how a gene mutation affects T cell function to promote immune disorders and then tested a treatment based on the discovery - successfully fixing donated immune cells from a 16-year-old boy with an abnormally low level of white blood cells called lymphopenia.

New genomic tools provide better understanding of the human immune system

When the body is under attack from pathogens, the immune system marshals a diverse collection of immune cells to work together in a tightly orchestrated process and defend the host against the intruders.
