Texto completoMycoplasma genitalium is a small human pathogen that causes non-gonococcal urethritis, cervicitis and several pelvic inflammatory diseases. It bears one of the smallest genomes in an autonomous living organism and, for this reason, it has become a bacterial model for a minimal cell. Moreover, this small pathogen has a singular mechanism for antigenic variation that relies on the homologous recombination between the main adhesins and genomic repeats scattered around the chromosome. Despite that M. genitalium was one of the first microorganisms to be fully sequenced, very little is known of its reduced genetic circuitry and gene regulation. Besides, the regulatory mechanisms controlling the antigenic variation process are obscure notwithstanding it is essential for immune evasion and persistence. In this doctoral thesis, we have studied the role of the MG428 protein (20), which is an alternative sigma factor of this small bacterium. MG428 recognizes a novel promoter sequence and activates transcription of a small regulon composed by genes coding for key recombination enzymes, genes coding for hypothetical proteins and also non-coding regions with unknown function. Moreover, single cell analyses confirmed that activation via 20 only takes place in a small subset of the population at the same time and showed a certain spatial association between 20-activated cells. The activity of this alternative sigma factor is crucial for the recombination capacity displayed by M. genitalium and the generation of genetic variants of the main antigens in this bacterium. In this thesis, we have also focused on the regulation of 20 activity by two uncharacterized proteins, named RrlA and RrlB (recombination regulatory loci). These regulators are under the transcriptional control of MG428 and stabilize 20 protein, allowing the progression of a feed-forward loop required for the activation of the 20 regulon. Mutants of either rrlA or rrlB have similar recombination deficiencies as observed in an MG_428 null mutant. Finally, we have observed an unprecedented horizontal transfer of DNA between two different M. genitalium strains. DNA transfer occurs from a donor cell overexpressing 20 to a recipient cell by means of homologous recombination. Overall, in this doctoral thesis we have shown a novel transcriptional regulator of recombination in M. genitalium that promotes antigenic variation through the activation of transcription of a unique regulon. 20 can also activate an unorthodox horizontal gene transfer system that may play a key role in the evolution and adaptation of these small pathogens.

Texto completo"therefore be on the fourth SCR or on the serine/theonine rich region. By sequencing genomic DNA from Cr(a-) people, Telen and colleagues showed that a mutation in the fourth SCR was responsible for Cr3 [13]. Considering the MAIEA results, the fourth SCR would be a good place to start looking for difference responsible for the WES polymorphism too. Other Cromer system antigens showed some inhibition with one of the BRIC antibodies [12]. MAIEA provided biochemical evidence that Esa is indeed a Cromer system antigen [12]. Esa was thought to be a Cromer related antigen because of the failure of anti-Esa to react with Cromer-null cells and from its behaviour with proteinaese treated cells [14]. These findings were supported by the observation that Esa was carried by a glycosyl phosphatidylinositol linked protein [15]. However, only a small amount of anti-Esa was available and,therefore, immunoblotting experiments could not be done. Strong positive results with BRIC 216 and 110 but a negative result with BRIC 230 suggested that Esa is located on DAF, possibly on the first SCR. Similarly, a negative result with BRIC 230 and Tca suggests that it too is on the first SCR (Table II) [12]. The results of the MAIEA tests for Cromer antigens are summarised in Table II. They agree with those known from DNA studies, Dra on SCR III [15,16,17] and Cr3 on SCR IV [13], and suggest the best places to look for those as yet undetermined. This demonstrates how MAIEA may be used to help narrow the field of study to determine the molecular basis of antigens. VARIATION IN EXPRESSION OF SOME Rh ANTIGENS We had hoped to apply MAIEA to Rh but to date the only antibodies to the D protein are of human origin, so MAIEA cannot yet be used to study the relationship of the D antigen to some of the low incidence antigens which appear to be markers of partial D antigens. The Rh antigen D is, after ABO, the most important antigen clinically because it is highly immunogenic. Until the introduction of Rh immunoprophylaxis, anti-D was the most frequent cause of haemolytic disease of the newborn and neonatal death [1]. Many Rh antigens are good immunogens. Since its initial recognition in the nineteen-forties, the Rh system has become very complex. There are 48 numbered antigens, that is serologically defined determinants, the numbers have reached 50 because two numbers have been declared obsolete [2,3,18,19]. Some antigens are polymorphic and others are of high or low incidence." En Transfusion Immunology and Medicine, 191. CRC Press, 1995. http://dx.doi.org/10.1201/9781482273441-10.
