Cytokine Gene Polymorphism in BCG Lymphadenopathy
Background: Tumor necrosis factor-beta or lymphotoxin-alpha (LT-α), IL-4 and IL-10 are determining factors in immunity against BCG. Allelic polymorphisms in the regulatory regions of their genes affect the rate of cytokine production and therefore, the host’s ability in BCG containment. Objective: To study the prevalence of –590 (C/T) and –592 (C/A) allelic distribution of IL-4 and IL-10 promo...
متن کاملGene Expression Contributes to the Recent Evolution of Host Resistance in a Model Host Parasite System
Heritable population differences in immune gene expression following infection can reveal mechanisms of host immune evolution. We compared gene expression in infected and uninfected threespine stickleback (Gasterosteus aculeatus) from two natural populations that differ in resistance to a native cestode parasite, Schistocephalus solidus. Genes in both the innate and adaptive immune system were ...
متن کاملThe relationship of host-mediated induced resistance to polymorphism in gene-for-gene relationships.
Gene-for-gene relationships are a common feature of plant-parasite interactions. Polymorphism at host resistance and parasite avirulence loci is maintained if there is negative, direct frequency-dependent selection on alleles of either gene. More specifically, selection of this kind is generated when the disease is polycyclic with frequent auto-infection. When an incompatible interaction occurs...
متن کاملRegulation of Mycobacterium bovis BCG and foreign body granulomas in mice by the Bcg gene.
Natural bactericidal resistance to Mycobacterium bovis BCG is under the control of a single gene, designated Bcg. Lung granuloma formation in susceptible (Bcgs) and resistant (Bcgr) mice was studied in two sets of Bcg-congenic systems, namely, the BALB/c (Bcgs)-C.D2 (BALB/c.Bcgr) pair and the B10.A (Bcgs)-B10.Ar (Bcgr) pair, by using BCG as well as foreign body granuloma-inducing agents (dextra...
متن کاملThe Effect of Herpes Simplex Virus Virion Host Shutoff Gene- a New Suicide Gene- on Tumor Cells
Background: The herpes simplex virus (HSV) UL41 gene product, virion host shutoff (Vhs) protein, mediates the rapid degradation of both viral and cellular mRNA. This ability suggests that Vhs protein can be used as a suicide gene in cancer gene therapy applications. The recent reports have shown that the degradation of cellular mRNA during herpes simplex infection is selective. RNA containing A...
