The expression of five cellular adhesion molecules (CAMs), CD54, CD58, CD11a, CD29 and CD49d, was studied in 113 B cell non-Hodgkin's lymphomas (NHL) and in normal B cells from 12 control lymph nodes. Rather than reporting the percentage of positive cells, which does not discriminate between NHL subtypes, we quantified the intensity of CAM expression using flow cytometry. Apart from CD49d the expression of all these CAMs was statistically different among the NHL subtypes as defined by the REAL classification. Low grade NHL-small lymphocytic, follicular and mantle cell lymphoma--which are derived from quiescent cells and show an indolent disease course, expressed low levels of CAMs. Conversely, high grade NHL-diffuse large cell lymphoma--which are derived from proliferating cells and are clinically aggressive, expressed high levels of CAMs. These results indicate that in malignant NHL B cell tumour growth and clinical aggressiveness may be related to the adhesive capacities of the tumour cells.

The structure of many native tissues consists of aligned collagen (Col) fibrils, some of which are further composited with dispersed hydroxyapatite (HAp) nanocrystals. Accurately mimicking this inherent structure is a promising approach to enhance scaffold biocompatibility in tissue engineering. In this study, biomimetic sheets composed of highly aligned Col fibrils were fabricated using a plastic compression and tension method, followed by the deposition of HAp nanocrystals on the surface via an alternate soaking method.

Influenza virus infects millions each year, contributing greatly to human morbidity and mortality. Upon viral infection, pathogen-associated molecular patterns activate pattern recognition receptors on host cells, triggering an immune response. The CD209 protein family, homologs of DC-SIGN (dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin), is thought to modulate immune responses to viruses.

A quarter of a century ago, sickle cell disease (SCD) was mainly viewed as a typical genetic disease inherited as a classical Mendelian trait. Therefore, the main focus concerning SCD was on diagnosis, meaning, genotyping, and identification of homozygous and heterozygous individuals carrying the relevant HbS mutant allele. Nowadays, it is well established that sickle cell disease is indeed the result of homozygosis for the HbS variant, although this single feature is not capable of explaining the highly diverse clinical presentation of SCD.

The development of efficient producers of recombinant pharmaceuticals based on plant cell suspension cultures is a pressing challenge in modern applied science. A primary limitation of plant cell cultures is their relatively low yield of the target protein. One strategy to enhance culture productivity involves reducing cell aggregation.
