Even with recent advances in therapy regimen, multiple myeloma patients commonly develop drug resistance and relapse. The relevance of targeting the PD-1/PD-L1 axis has been demonstrated in pre-clinical models. Monotherapy with PD-1 inhibitors produced disappointing results, but combinations with other drugs used in the treatment of multiple myeloma seemed promising, and clinical trials are ong...

The effect of human cytomegalovirus (HCMV) infection on cellular mRNA accumulation was analyzed by gene chip technology. During a 48-h time course after infection of human diploid fibroblasts, 1,425 cellular mRNAs were found to be up-regulated or down-regulated by threefold or greater in at least two consecutive time points. Several classes of genes were prominently affected, including interfer...

Objective. Rheumatoid arthritis (RA) patients are at increased risk of latent tuberculosis infection (LTBI) but there are no clear guidelines for LTBI screening with Tuberculin Skin Test (TST) or Quantiferon TB Gold testing (QFT-G). Methods. A retrospective study was conducted in a high risk, largely foreign-born, inner city, RA population. After screening 280 RA patients, 134 patients who had ...

Active-targeted delivery to lymph nodes represents a major advance toward more effective treatment of immune-mediated disease. The MECA79 antibody recognizes peripheral node addressin molecules expressed by high endothelial venules of lymph nodes. By mimicking lymphocyte trafficking to the lymph nodes, we have engineered MECA79-coated microparticles containing an immunosuppressive medication, t...

The most effective treatment for gastric cancer is complete surgical resection with lymphadenectomy. However, a number of patients experience recurrence of the cancer even after curative surgery. This review focuses on comparative trials studying the use of adjuvant therapy with chemotherapy plus immunotherapy in the treatment of patients with curatively resected gastric cancer. Preoperative an...

BACKGROUND In the search for new therapies novel drugs and medications are being discovered, developed and tested in laboratories. Highly diluted substances are intended to enhance immune system responses resulting in reduced frequency of various diseases, and often present no risk of serious side-effects due to its low toxicity. Over the past years our research group has been investigating the...

There is a general consensus that the elderly do not respond as well to vaccination as the young, but robust studies are few and far between. Most refer to influenza vaccination, but even here, adequate immunological and clinical data are surprisingly thin on the ground. The meta-analysis by Goodwin et al. from 2006 is still the most comprehensive that we have. They reviewed 31 antibody respons...

A fundamental question in biology is how multicellular organisms distinguish self and non-self. The ability to make this distinction allows animals and plants to detect and respond to pathogens without triggering immune reactions directed against their own cells. In plants, inappropriate self-recognition results in the autonomous activation of the immune system, causing affected individuals to ...

In 1991, the World Health Assembly adopted a resolution to attain the goal of global elimination of leprosy as a public health problem by the year 2000, based on universal access to multidrug therapy established by the WHO. The WHO multidrug therapy recommendation was not based on clinical trial results, but was based on all scientific knowledge available at the time and incorporated some finan...

Gut immunocompetence involves immune, stress and regenerative processes. To investigate the determinants underlying inter-individual variation in gut immunocompetence, we perform enteric infection of 140 Drosophila lines with the entomopathogenic bacterium Pseudomonas entomophila and observe extensive variation in survival. Using genome-wide association analysis, we identify several novel immun...
