Healthy adults with shorter telomere length more likely to develop upper respiratory infection

Among healthy adults who were administered a cold virus, those with shorter telomere length (a structure at the end of a chromosome) in certain cells were more likely to develop experimentally-induced upper respiratory infection than participants with longer telomeres, according to results of preliminary research published in the February 20 issue of JAMA.

Infusions of regulatory T cells turn off autoimmune attack on joints

Farber Cancer Institute scientists have demonstrated a new strategy for treating autoimmune disease that successfully blocked the development of rheumatoid arthritis in a mouse model. They say it holds promise for improved treatment of arthritis and other autoimmune disorders in people.

HIV infection rate in MSM in England and Wales remains unchanged despite improved prevention measures

The rate of new HIV infections among men who have sex with men (MSM) in England and Wales has remained unchanged over the past decade despite an almost four-fold increase in HIV testing, rising treatment coverage, and a 20% shortening of time-to-diagnosis, according to new research published Online First in The Lancet Infectious Diseases.

HIV-positive patients have higher incidence of non-melanoma skin cancers

HIV-positive patients have a higher incidence of non-melanoma skin cancers, according to a Kaiser Permanente study that appears in the current online issue of the Journal of the National Cancer Institute. Specifically, basal cell and squamous cell carcinomas occur more than twice as often among HIV-positive individuals compared to those who are HIV-negative.

Current smokers with HIV more likely to get bacterial pneumonia

Bacterial pneumonia is one of the commonest and most serious infections occurring in people infected with HIV. A metanalysis of cohort and case control studies published in BioMed Central's open access journal BMC Medicine finds that current smokers with HIV were at double the risk of bacterial pneumonia than non-smoking counterparts, but that when people stopped smoking their risk was reduced.

Early treatment during primary HIV infection shows promise

Two papers in The New England Journal of Medicine suggest that starting antiretroviral treatment early after HIV infection is diagnosed may improve patients’ immune response, boosting the initial recovery of the immune system and delaying progression of the disease.

Scientists identify new mechanism that turns CD4 helper T lymphocytes into killer cells

A research team led by the La Jolla Institute for Allergy & Immunology has discovered the mechanism that enables CD4 helper T cells to assume the more aggressive role of killer T cells in mounting an immune attack against viruses, cancerous tumors and other damaged or infected cells.

Mature CD4+ helper T lymphocytes can be re-programed to gain killing functions

The fate of mature T lymphocytes might be a lot more flexible than previously thought. New research from the RIKEN Center for Allergy and Immunology (RCAI) in Japan and La Jolla Institute for Allergy and Immunology (LIAI) in the USA shows for the first time that mature CD4+ helper T lymphocytes can be re-programed to become killer-like CD8+ T lymphocytes and gain killing functions.

Experimental vaccine elicits antibodies that can protect against Ebola virus infection

Researchers at the National Institutes of Health (NIH) and Oregon Health & Science University (OHSU) have found that an experimental vaccine elicits antibodies that can protect nonhuman primates from Ebola virus infection.

Vaccine gives HIV patients a long-term boost

A functional cure for HIV-1 seems feasible after research shows that an immunotherapeutic vaccine demonstrated long-term efficacy at reducing viral load when administered to patients in the early stages of disease.

Crofelemer receives FDA approval for treatment of HIV associated diarrhea

Glenmark Pharmaceuticals Limited announced today that the US Food and Drug Administration has provided Marketing approval to its partner in US, Salix Pharmaceuticals Limited, for Crofelemer 125 mg delayed-release tablets for the symptomatic relief of non-infectious diarrhea in patients with human immunodeficiency virus (HIV)/ acquired immune deficiency syndrome (AIDS) on anti-retroviral therapy (ART).

Insights into tissue-based T cells

US researchers have, for the first time, characterized T cells located in human tissues, rather than in the blood.

Lymphocyte clue to multiple sclerosis drug response

Patients with rapid recovery of CD4-positive T cells after alemtuzumab treatment for multiple sclerosis are at risk for disease progression or relapse, research suggests.

SLU researchers to study physiological and biochemical functions in lupus

Two researchers at Saint Louis University's division of rheumatology in the department of internal medicine have been awarded a $1.8 million NIH grant to study the physiological and biochemical functions in lupus, an autoimmune disease, and develop possible new medications for its treatment.

Children with HIV more likely to develop atherosclerosis

Children with HIV have a 2.5 fold increased risk of atherosclerosis, according to research presented at EUROECHO and other Imaging Modalities 2012. Antiretroviral treatment, lipid lowering drugs and prevention with healthy lifestyles are needed to prevent early death from cardiovascular disease.

Inovio's SynCon DNA vaccine effective at inducing CD8+ T cell responses specific to CMV

Inovio Pharmaceuticals, Inc. announced today that testing of multiple synthetic vaccine constructs for cytomegalovirus (CMV) induced robust T cells in mice, demonstrating the potential for a SynCon DNA vaccine to treat this virus that causes infant death and congenital abnormalities, is associated with cerebral palsy and brain tumors, and is the most common viral infection in organ transplant recipients. CMV is also associated with numerous inflammatory diseases and cancers, and is implicated in hypertension, a major risk factor for cardiovascular diseases.
