Celiac disease (CD) is an immune-mediated disease affecting the small intestine. The only treatment strategy for CD is the gluten-free diet (GFD). One of the more common mental disorders in CD patients is major depressive disorder (MDD).

Increased HPA axis activity can be observed during chronic stress, which plays a key role in the pathophysiology of depression. Overactivity of the HPA axis occurs in major depressive disorder (MDD), leading to cognitive dysfunction and reduced mood.

The chronic stress contributes to the formation of oxidative stress in the parts of the brain involved in the development of depression and AD. The scientific literature reports the significant role of antioxidants, which are highly effective in treating these diseases.

The data obtained from site-directed mutagenesis in transient transfection experiments indicate that the Sp1 sites at positions -641, -635, and -313, CF1/YY1 elements at positions -586 and -357, and the AP-1 motif at -276 within the-660/-233 fragment of the human FCGRT promoter (hFCGRT) participate in the regulation of human FCGRT in all selected cell lines. However, their individual contribution to promoter activity is not equivalent.

Objective: To estimate the prevalence and to describe clinical characteristics of tic disorders in 12-15 year old Warsaw schoolchildren.
Method: Children attending 24 randomly selected schools were screened by inquiring their parents and teachers. Children indicated as tic-positive by the screening procedure were investigated using semi-structured questionnaires and the Polish version of YGTSS scale.
This review summarizes the status of our knowledge on the structure, expression and function of CD1 proteins. An endosomal and non-endosomal pathways of CD1 antigen presentation are also described.

The human homologue of FcRn was first found in the placenta, where is presumably involved in transfer of maternal IgG to the fetus. FcRn has since been found in capillary endothelium, intestinal epithelium and other tissues.

These are: disturbance of reciprocal social interaction, disturbance of communication and restriction of normal variation in behaviour and interests. The criteria used in the ICD-10 include all these domains.

Transient transfection of the CAT constructs revealed that there was promoter activity in the region -660 to +300 of the 5'-flanking sequence. Electrophoretic mobility-shift assays showed that there are functional binding sites for Sp1 or Sp1-like factors, AP1 or a related factor, and additional unidentified proteins in the promoter region.

The neonatal Fc receptor, FcRn, is expressed in human placental syncytiotrophoblast, capillary endothelium, intestinal epithelium, and other tissues. By analogy with its role in the mouse, human FcRn is expected to transport maternal IgG to the foetus, and protect circulating IgG from catabolism. The larger subunit of FcRn is homologous to the alpha chains of the major histocompatibility complex (MHC) class I proteins, but is encoded outside the MHC on chromosome 19.

We have found that human glycophorin and asialoglycophorin interacted with human non-immune IgG. To characterize quantitatively the interaction between glycophorin and IgG we elaborated a direct solid-phase radioimmunoassay. We showed that the binding of IgG was reversible and saturable within the range of IgG concentrations used.

The aim of the presented work was to find out whether the Fc gamma receptor from human placental syncytiotrophoblast plasma membranes in its native membrane-bound state is composed of more subunit chains than previously found in our laboratory in the purified receptor. The chains might be lost during the purification procedure with the use of various chaotropic reagents, e.g.

Binding of ligands to cell surface receptors may induce an interaction of the receptors with the cell cytoskeleton. This interaction may decrease the solubility of the receptors in nonionic detergents. We studied effect of binding of various 125I-labeled immunoglobulin ligands to Fc gamma receptors on guinea pig peritoneal macrophages and human placental syncytiotrophoblast plasma membranes on an interaction of these receptors with the cytoskeletal matrix.

The rabbit antibodies were of IgG class and their F(ab')2 fragment interacted with Fc receptors in solubilized form and membrane-bound, as well. Immunological reactivity of the antibodies with Fc gamma R was demonstrated using immunodiffusion, solid-phase immunoassay, and ELISA.
