Hemizygous nonsense variant in the moesin gene leads to a new autoimmune phenotype of Immunodeficiency 50.

Here, we present the findings of an investigation involving two male siblings with juvenile total tooth loss, early-onset chronic leg ulcers, and autoimmune thyroiditis, as well as focal segmental glomerulosclerosis with associated pulmonary emphysema in one and diabetes mellitus in the other. The clinical picture and lupus anticoagulant, cryoglobulin, and cold agglutinin positivity suggested the diagnosis of antiphospholipid syndrome. Flow cytometry analysis showed immunophenotypes consistent with immune dysregulation: a low number of naive T cells, elevated CD4 T cell counts, and decreased CD8 T-cell counts were detected, and more than half of the T-helper population was activated.

Drug Delivery through the Psoriatic Epidermal Barrier-A "Skin-On-A-Chip" Permeability Study and Ex Vivo Optical Imaging.

Psoriasis is a chronic inflammatory disease with unmet medical needs. To clarify potential therapeutic targets, different animal models have been developed. In the current study, imiquimod-induced psoriasiform dermatitis was used for monitoring the changes in skin thickness, transepidermal water loss, body weight, blood perfusion and drug permeability for a topical cream formulation of caffeine, both in wild type and in knock out mice.

Expression Patterns of Clock Gene mRNAs and Clock Proteins in Human Psoriatic Skin Samples.

Psoriasis is a systemic inflammatory skin disorder that can be associated with sleep disturbance and negatively influence the daily rhythm. The link between the pathomechanism of psoriasis and the circadian rhythm has been suggested by several previous studies. However, there are insufficient data on altered clock mechanisms in psoriasis to prove these theories.

A Localized Aldara (5% Imiquimod)-Induced Psoriasiform Dermatitis Model in Mice Using Finn Chambers.

The expanding number of research studies utilizing the imiquimod-induced psoriasiform dermatitis model attests to the usefulness of this procedure. Advantages of this model include rapid development of the skin response and cost-effectiveness. A major limitation is that application of imiquimod cream over large areas of skin, as well as licking and ingestion of the cream, may lead to severe systemic inflammation, which can cause a general decline in health, splenomegaly, and death.

Methodological refinement of Aldara-induced psoriasiform dermatitis model in mice.

Imiquimod (IMQ)-induced skin inflammation is currently the most widely accepted psoriasis animal model, however, it features several limitations. We have modified the IMQ-model to minimize its systemic effects towards effectively maintaining the characteristic skin reactions. The original protocol (OP) uses 62.

Mapping of crown gall resistance locus Rcg1 in grapevine.

Agrobacteria are efficient plant pathogens. They are able to transform plant cells genetically resulting in abnormal cell proliferation. Cultivars of Vitis vinifera are highly susceptible to many virulent Agrobacterium strains but certain wild Vitis species, including Vitis amurensis have resistant genotypes.
