In eukaryotic cells, the nuclear envelope separates the genomic DNA from the cytoplasmic
space and regulates protein trafficking between the two compartments. This barrier is only …

Cell migration has two opposite faces: although necessary for physiological processes such
as immune responses, it can also have detrimental effects by enabling metastatic cells to …

Salivary gland tumors constitute a highly heterogeneous histopathologic group. There are
few epidemiological studies of large series of benign and malignant salivary gland tumors in …

To initiate adaptative cytotoxic immune responses, proteolytic peptides derived from
phagocytosed antigens are presented by dendritic cells (DCs) to CD8 + T lymphocytes through a …

Dendritic cells (DCs) sample peripheral tissues of the body in search of antigens to present
to T cells. This requires two processes, antigen processing and cell motility, originally thought …

Background: Large osseous defects of the posterosuperior aspect of the humeral head can
engage the glenoid rim and cause recurrent instability after arthroscopic Bankart repair for …

The most rapid species radiations have been reported from ‘evolutionary laboratories’, such
as the Andes and the Cape of South Africa, leading to the prevailing view that diversification …

Dendritic cell (DC) migration in peripheral tissues serves two main functions: antigen sampling
by immature DCs, and chemokine-guided migration towards lymphatic vessels (LVs) on …

Mediterranean-type ecosystems (MTEs) are located today in southwestern Australia, the
Cape Region of South Africa, the Mediterranean Basin, California, and central Chile. These …

Diagnosis of pigmented lesions of the oral cavity and perioral tissues is challenging. Even
though epidemiology may be of some help in orientating the clinician and even though some …
