A computerized model for the self-non-self discrimination at the level of the T(h) (Th genesis). I. The origin of 'primer' effector T(h) cells.

The ability of the immune system to respond by ridding a pathogen without debilitating the host depends upon the ability of the effector T(h) (eT(h)) to make a discrimination between 'self' and 'non-self' antigens. This ability is somatically learned and involves the sorting of the somatically generated random repertoire of initial state T(h) (iT(h)) into two classes of specificity: one, anti-self, the functional expression of which must be inactivated; the other, anti-non-self, the functional expression of which must be activated. We propose a model for the origin of a sufficiency of eT(h) anti-non-self and an insufficiency of eT(h) anti-self based on two postulates. (i) An antigen-independent pathway to a priming level of eT(h) anti-non-self under conditions where iT(h) anti-self are effectively deleted by interaction with self. This state is established during a window of fetal development and maintained throughout life because self is persistent. (ii) Associative recognition of antigen (peptide-MHC class II) on an antigen-presenting cell between iT(h) and 'primer' eT(h) that results in the rapid induction of an effective level of helper activity to non-self antigen. A computer simulation is provided that enables evaluation of this model.

Differential accessibility at the kappa chain locus plays a role in allelic exclusion.

Gene rearrangement in the immune system is always preceded by DNA demethylation and increased chromatin accessibility. Using a model system in which rearrangement of the endogenous immunoglobulin kappa locus is prevented, we demonstrate that these epigenetic and chromatin changes actually occur on one allele with a higher probability than the other. It may be this process that, together with feedback inhibition, serves as the basis for allelic exclusion.

Cloning and expression analysis of two mucin-like genes encoding microfilarial sheath surface proteins of the parasitic nematodes Brugia and Litomosoides.

In several filarial genera the first stage larvae (microfilariae) are enclosed by an eggshell-derived sheath that provides a major interface between the parasite and the host immune system. Analysis of the polypeptide constituents of the microfilarial sheath from the cotton rat filaria Litomosoides sigmodontis identified two abundant surface glycoproteins: Shp3a and Shp3. The corresponding genes and the orthologues of the human parasite Brugia malayi and the rodent filaria Brugia pahangi were cloned and sequenced. They encode secreted, mucin-like proteins with N-terminal Ser/Thr-rich repeats and a C-terminal anchor domain rich in aromatic amino acids. About 75% of the protein molecular masses result from post-translational modifications. The Ser/Thr-rich motifs are supposed to serve as targets for dimethylaminoethanol-phosphate substitutions. These modifications were detected only on the sheaths of the late developmental stage of stretched microfilariae, corresponding with the expression of the proteins in the epithelium of the distal part of the uterus and the specific transcription of shp3 and shp3a in the anterior female worm segment. Genomic analysis of all three species demonstrated a conserved linkage of the two genes. Their transcripts undergo cis- and trans-splicing. The transcription start sites of the primary transcripts were determined for the L. sigmodontis genes. The core promoter regions are remarkably conserved between the paralogue genes Ls-shp3a and Ls-shp3 and their orthologues in Brugia, implicating conserved regulatory elements.

Several epidemiologic studies have suggested an association between exposure to extremely low frequency (ELF) magnetic fields (MFs) and cancer in adults and children. A possible target of MFs is the immune system. The effects of the exposure to ELF MFs on the immunological functions of human peripheral blood mononuclear cells (PBMCs) obtained from healthy male volunteers were assessed by measuring the natural killer (NK) and lymphokine activated killer (LAK) activities and the production of interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2), and interleukin-10 (IL-10). The PBMCs were exposed to three different MF: linearly polarized (vertical), circularly polarized, and elliptically polarized, at 50 and 60 Hz. Magnetic flux densities were set at 500, 100, 20, and 2 microT (rms) for vertical field and at 500 microT (rms) for the rotating fields. Using cytotoxicity assay and enzyme-linked immunosorbent assay (ELISA) for cytokine production, we could not find any effects of ELF MFs on the cytotoxic activities and the cytokines production of human PBMCs. 2002 Wiley-Liss, Inc.

Sudden infant death syndrome is the most common cause of postneonatal infant mortality in the developed world. It is a diagnosis of exclusion with peak age of incidence between 2 and 6 mo. Fifty to 63% of these infants have a preexisting upper respiratory tract infection before death. We hypothesized that the immature immune system may be altered by a primary infection, preventing a protective response after secondary challenge. To mimic dual infection, we used a nonlethal strain of a rat-adapted influenza A virus and a sublethal dose of endotoxin to establish a model that results in pathology and death in 12-d-old rat pups similar to that seen in infants dying of sudden infant death syndrome. Mortality only occurred when specific criteria such as timing between infectious insults and developmental age of the pup were met. Results suggest that mortality is caused by a rapid systemic shock event rather than lung-specific damage. Gross pathologic findings such as lung petechiae and liquid blood around the heart on necropsy were consistent with those seen in infants dying of sudden infant death syndrome. Histopathologic lesions including subendocardial hemorrhage and mild cortical thymocyte necrosis were found with greater severity and frequency in dually challenged animals. Macrophage subpopulation in rat-adapted influenza A virus-inoculated animals was significantly elevated in the spleen at the time of death. Our model suggests that the developing immune system can be primed to respond in an exaggerated way to a second immune challenge resulting in unexpected death.

Hair growth is a sophisticated biological process, which is still not thoroughly understood. A multitude of therapeutic measures, including drugs, surgery, and suppelements have been made available, and used. However, due to the diversity of the problems underlying hair loss, there is no single solution for all hair loss cases. Most of chemical drugs and hair transplantation surgeries are not free from varying degrees of undesirable side effects on health.

We only know by anecdotal observations. There has been no clinical trials nor placebo controlled statistical analysis on the efficacy of Hair Million on hair loss and hair growth. For the clinically tested, FDA approved prescription medication, check Buy Propecia Online.

DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones) or estrogens (female hormones) in the cells.
