Sensitization to specific olive pollen-allergens (Ole e 2 and 10) has been correlated with a clinical pattern of asthma. This study analyzes the association between several polymorphims ofTNFA(G-308A,C-857T, andC-1031T),IL10(C-571AandA-1117G), andTGFB(C-509-T) and these sensitizations. These polymorphisms were genotyped by allelic discrimination, in olive pollen-allergic patients (phenotyped for specific Ole e 2 and 10 sensitizations) and healthy controls. Levels of serum-soluble cytokines were correlated with specific genotypes and clinical phenotypes. The results showed that heterozygousTGFB C-509Tgenotype, besides having the lowest sera TGF- levels, was significantly increased in olive pollen-allergic patients compared with controls. According specific sensitizations,CCgenotype ofIL10 C-571Acould be a protective factor for Ole e 2 sensitization and mainly for asthmatic Ole e 2 sensitized patients compared with asthmatic non-Ole e 2 sensitized patients (OR: 0.26,P=0.008). In contrast, heterozygousCAgenotype was increased in Ole e 2 asthmatic subjects compared to asthmatic non-Ole e 2 sensitized patients. Lastly, heterozygousTNFA G-308Agenotype was associated with Ole e 10 sensitization (OR: 2.5,P=0.04). In conclusion, these results suggest a role of TGF-β1 in olive-pollen sensitization and TNF-αand IL-10 genotypes in the asthma induced by specific olive-pollen allergens.

ABSTRACT Pemphigus is an autoimmune blistering disease characterized by a loss of cell adhesion result in acantholysis. Genetic factors and immunologic factors such as cytokines particularly IL-1α, IL-10, TNF-α, and TGF-β may counterpart to developing of Pemphigus. The aim of this study was to evaluate. The concentration of IL-1α, IL-10, TNF-α, TGF-α in serum of pemphigus vulgaris (PV) patients and normal individuals. Material and methods In this analytic and descriptive study 25 patients with pemphigus vulgaris (in active phase) and 25 healthy persons were examined. Serum samples of two groups were obtained and the level of IL-1α, IL-10, TNF-α and TGF-β were measured by ELISA technique. The data were analyzed statistically by independent T test (α = 0/05). Results All cytokines tested, showed higher concentration in patient's sera comparing to healthy control individuals. The level of IL-1α (p = 0.004), TNF-α (p = 0.008) and TGF-β (p = 0.009) were statistically different in two experimental groups, There was no significant difference in IL-10 level (p = 0.605). Conclusion Cytokines such as IL-1α, IL-10, TNF-α and TGF-β probably have a role in pathogenesis of PV. Further comprehensive studies are suggested to confirm these findings.

We have examined the role of the immunomodulatory cytokine transforming growth factor (TGF)-β in the resolution and pathology of malaria in BALB/c mice. Circulating levels of TGF-β, and production of bioactive TGF-β by splenocytes, were found to be low in lethal infections with Plasmodium berghei. In contrast, resolving infections with P. chabaudi chabaudi or P. yoelii were accompanied by significant TGF-β production. A causal association between the failure to produce TGF-β and the severity of malaria infection was demonstrated by treatment of infected mice with neutralizing antibody to TGF-β, which exacerbated the virulence of P. berghei and transformed a resolving P. chabaudi chabaudi infection into a lethal infection, but had little effect on the course of P. yoelii infection. Parasitemia increased more rapidly in anti–TGF-β–treated mice but this did not seem to be the explanation for the increased pathology of infection as peak parasitemias were unchanged. Treatment of P. berghei–infected mice with recombinant TGF-β (rTGF-β) slowed the rate of parasite proliferation and prolonged their survival from 15 to up to 35 d. rTGF-β treatment was accompanied by a significant decrease in serum tumor necrosis factor α and an increase in interleukin 10. Finally, we present evidence that differences in TGF-β responses in different malaria infections are due to intrinsic differences between species of malaria parasites in their ability to induce production of TGF-β. Thus, TGF-β seems to induce protective immune responses, leading to slower parasite growth, early in infection, and, subsequently, appears to downregulate pathogenic responses late in infection. This duality of effect makes TGF-β a prime candidate for a major immunomodulatory cytokine associated with successful control of malaria infection.
