Distinct patterns of neonatal gut microflora in infants in whom
atopy was and was not developing.
Kalliomaki M, Kiriavainen P, Eerola E, Kero P, Salminen S, Isolauri E.
RESULTS: • Atopic sensitization was observed in 22 (29%) of 76 children. At 3 weeks,
the bacterial cellular fatty acid profile in fecal samples differed significantly between infants in whom atopy was and was not developing (P =.005). By using fluorescence in situ hydridization, atopic subjects had more clostridia (geometric mean [95% confidence interval]: 9.3 x 10(7) [3.8-22.9 x 10(7)] vs 3.3 x 10(7) [1.8-6.1 x 10(7)], P =.04) and tended to have fewer bifidobacteria (1.8 x 10(9) [0.4-7.6 x 10(9)] vs 6.1 x 10(9) [2.5-14.6 x 10(9)], P =.11) in their stools than nonatopic subjects, resulting in a reduced ratio of bifidobacteria to clostridia (P =.03).
CONCLUSION: • Differences in the neonatal gut microflora precede the development of
atopy, suggesting a crucial role of the balance of indigenous intestinal bacteria for the maturation of human immunity to a nonatopic mode.

• We therefore aimed at comprehensively investigating local or systemic levels of anti-microbial and anti-food Abs in IBD patients. For this purpose, we analyzed in parallel serum and fecal Abs specific for dietary and microbial antigens in a cohort of IBD patients and controls.

Results • Serum anti-Saccharomyces cerevisiae antibodies (ASCA) and anti-B.
fragilis IgG and IgA levels were increased in CD patients whereas antibody (Ab) levels against E. coli and food antigens were not significantly different within the patient groups and controls
• One important finding of our study is that we did not find any correlation between food-specific Ab levels and clinical symptoms. Our data does not support the idea that measurements of anti-food specific IgG or IgA is of any clinical relevance for patients suffering from CD or UC. In particular, it does not predict the presence of food intolerance.

• Acute exacerbation of disease does not correlate with antibody levels, however enhanced ASCA and other anti-microbial Ab levels correlate with more complicated disease courses and anti-TNF-α therapy, It has been shown that microbial-specific IgA mediates gut homeostasis in animal models and might therefore have anti-inflammatory functions in IBD.

• In summary, our study reveals that CD, UC and AGE
patients as well as non-inflammatory controls have distinct patterns of IgG and IgA against food and microbial antigens in serum and feces suggesting differentially regulated immune responses towards intestinal antigens. However, food-specific Abs have not yet been proven to be a valuable biomarker for IBD or food intolerance.

Gliadin Induces Neutrophil Migration via
Engagement of the Formyl Peptide Receptor,
FPR1.
Results In vivo intestinal luminal injection of PT-gliadin induces an immediate and substantial recruitment of neutrophils. Increased intestinal permeability favors the access of gliadin and other macromolecular antigens from the intestinal lumen into the lamina propria where the host, by interpreting them as danger signals, will respond with first-line defense mechanisms such as neutrophil recruitment to the site of exposure.
CXCR3-/- neutrophil chemotaxis using EZ-TAXIScan chemotactic assay. The EZ-TAXIScan chemotactic assay was used for direct visualization of chemotaxis of CXCR3-/- neutrophils to either PT-gliadin (lower panel) or fMet-Leu-Phe (middle panel). PBS (upper panel) was used as a negative control. PT-gliadin and fMet-Leu-Phe induced similar chemotactic responses as C57BL/6 wild-type neutrophils (see S2 movie), indicating that neutrophil chemotaxis is independent of PT-gliadin binding to CXCR3. Frames were taken every 15 seconds.
Macrophage activity in semen is significantly
correlated with sperm quality in infertile men.
“The presence of leucocytes within semen has the potential to impair sperm function. Neutrophils and macrophages make up 95% of seminal leucocytes, with both having the ability to damage sperm via the generation of reactive oxygen species, proteases and the induction of apoptosis…..We were able to confirm for the first time that seminal plasma does indeed contain neopterin and that the levels of this macrophage activity marker are threefold higher in infertile than fertile men.”

• It is, however, difficult to discriminate between the consequences of the activation of resident macrophages and the activation of infiltrating neutrophils: these two cell types can secrete similar panels of molecules and antimicrobial products. Nonetheless, the severity of IC induced inflammation is closely linked to the extent of neutrophil infiltration, suggesting that this cell type is responsible for most of the observed symptoms.

Chronic activation of the innate immune
system may underlie the metabolic syndrome
Most importantly, activation of this system leads to fundamental changes in body metabolism. In this regard, it is notable that pro-inflammatory cytokines are major stimulants of the hypothalamic-pituitary-adrenal axis, leading to increased cortisol secretion and inhibition of sex hormone production.

About our Speakers
-Philip Regal, Biologist
“Plants are little biochemical factories that produce scores of bioactive compounds in order to mess up the metabolism of a great variety of predators and pathogens. That’s why all the first drugs were discovered in plants. Even in small amounts some plant chemicals are good for us and some are dangerous, so ethnobotanists seek knowledge from local tribal people about which are which.”
