Immunoprotection of Recombinant Leptospiral Immunoglobulin-Like Protein A against Leptospira interrogans Serovar Pomona Infection

Abstract: We previously reported the cloning and characterization of leptospiral immunoglobulin-like proteins LigA and LigB of Leptospira interrogans. LigA and LigB are conserved at the amino-terminal region but are variable at the carboxyl-terminal region. Here, we evaluate the potential of recombinant LigA (rLigA) as a vaccine candidate against infection by L. interrogans serovar Pomona in a hamster model. rLigA was truncated into conserved (rLigAcon) and variable (rLigAvar) regions and expressed in Escherichia coli a… Show more

“…Ideally an effective vaccine would induce induce cross-protection against the range of serovars of public health importance. Encorauging data using recombinant proteins and DNA vaccines in different animal models has already been published [13][14][15][16][17][18][19].…”

“…Devido à localização, essas proteínas podem participar das interações patógeno-hospedeiro e, ainda, servir de alvo para o sistema imune. Nesse sentido, algumas proteínas de membrana, analisadas por programas de bioinformática têm sido identificadas como possíveis candidatos vacinais em modelo animal (ATZINGEN et al, 2010;ATZINGEN et al, 2012;CULLEN et al, 2002;GAMBERINI et al, 2005;HAAKE et al, 1999;NASCIMENTO et al, 2004a;NASCIMENTO et al, 2004b;PALANIAPPAN et al, 2006;REN et al, 2003;YAN et al, 2009).…”

“…A partir dessas evidências experimentais, várias outras proteínas de leptospiras têm sido testadas como candidatos vacinais. LipL32, a proteína imunodominante de leptospiras, já foi testada na forma de vacina de DNA (BRANGER et al, 2005), BCG como veículo vivo expressando LipL32 (SEIXAS et al, 2007), LipL32 coadministrada com a subunidade B da toxina LT de E. coli (GRASSMANN et al, 2012) e fusionada a LigANI (LUCAS et al, 2011 (FAISAL et al, 2008;FAISAL et al, 2009;PALANIAPPAN et al, 2006;SILVA et al, 2007;YAN et al, 2009 (HANAHAN, 1983). Foram utilizados 5µL do produto de ligação para 50 µL de bactérias competentes, que foram incubadas por 30 minutos em banho de gelo e, em seguida, submetidas a um choque térmico, por 2 minutos a 42 ºC.…”
