Association between Galectin Levels and Neurodegenerative Diseases: Systematic Review and Meta-Analysis.

Galectins are a family of proteins with an affinity for β-galactosides that have roles in neuroprotection and neuroinflammation. Several studies indicate that patients with neurodegenerative diseases have alterations in the concentration of galectins in their blood and brain. However, the results of the studies are contradictory; hence, a meta-analysis is performed to clarify whether patients with neurodegenerative diseases have elevated galectin levels compared to healthy individuals.

Clinical evaluation, serological response and lesions generated by the A/Mexico/La Gloria-3/2009/H1N1 and A/swine/New Jersey/11/1976/H1N1 influenza viruses in colostrated and non-colostrated pigs.

Influenza A viruses cause respiratory disease in piglets, and maternal immunity plays an important role in protecting against Influenza virus infection. Nevertheless, in the presence of high levels of maternal antibodies against influenza, an adequate immune response is not developed. In this study, the effect of maternal antibodies against the swine influenza A/swine/New Jersey/11/1976/H1N1 virus (swH1N1) on clinical presentation, serological response, and lesions produced in colostrated and non-colostrated pigs was evaluated in pigs infected with the human influenza A/Mexico/La Gloria-3/2009/ H1N1 (pH1N1) and swH1N1 viruses.

Serological study of influenza viruses in veterinarians working with swine in Mexico.

Humans and swine are both affected by influenza viruses, and swine are considered a potential source of new influenza viruses. Transmission of influenza viruses across species is well documented. The aim of this study was to evaluate the seroprevalence of different influenza virus subtypes in veterinarians working for the Mexican swine industry, using a hemagglutination inhibition test.

Co-infection of classic swine H1N1 influenza virus in pigs persistently infected with porcine rubulavirus.

Porcine rubulavirus (PorPV) and swine influenza virus infection causes respiratory disease in pigs. PorPV persistent infection could facilitate the establishment of secondary infections. The aim of this study was to analyse the pathogenicity of classic swine H1N1 influenza virus (swH1N1) in growing pigs persistently infected with porcine rubulavirus.

Influenza vaccine: development of a novel intranasal and subcutaneous recombinant adjuvant.

The synthetic peptide GK-1, derived from Taenia crassiceps, enhances the protection induced by human influenza vaccine in both young and aged mice. Herein, the adjuvant properties of GK-1 fused to the pVIII protein of a heat-inactivated phagemid vector (FGK1) when co-administered with the influenza vaccine were assessed, to evaluate its feasibility as a low-cost adjuvant. In mice, FGK1 significantly increased the expected IgG and IgA anti-influenza antibody levels both in sera and in bronchoalveolar fluids when intranasally or subcutaneously co-administered with influenza vaccine.

Retrospective serological survey of influenza viruses in backyard pigs from Mexico City.

Background: In the present study, we analyzed the presence of antibodies to four different influenza viruses (pH1N1, hH1N1, swH1N1, and swH3N2) in the sera of 2094 backyard pigs from Mexico City. The sera were obtained between 2000 and 2009.

Objectives: The aim of this study was to perform a retrospective analysis of the 2000-2009 period to determine the seroprevalence of antibodies against pH1N1, hH1N1, swH1N1, and swH3N2 viruses in sera obtained from backyard pigs in Mexico City.

Characterization of an influenza A virus in Mexican swine that is related to the A/H1N1/2009 pandemic clade.

In the spring of 2009, swine-origin influenza H1N1pdm09 viruses caused the first influenza pandemic of this century. We characterized the influenza viruses that circulated early during the outbreak in Mexico, including one newly sequenced swine H1N1pdm09 virus and three newly sequenced human H1N1pdm09 viruses that circulated in the outbreak of respiratory disease in La Gloria, Veracruz. Phylogenetic analysis revealed that the swine isolate (A/swine/Mexico/4/2009) collected in April 2009 is positioned in a branch that is basal to the rest of the H1N1pdm09 clade in two (NP and PA) of the eight single-gene trees.
