'Carica papaya leaves have been used for traditional treatment of dengue fever and have been reported to exhibit an immunomodulatory activity by affecting the level of cytokine production in vitro and in vivo. Due to the lack of adequate in vivo evidence in dengue disease model, the present study was ... More

'Worldwide resurgence of whooping cough calls for improved, next-generation pertussis vaccines that induce broad and long-lasting immunity. A mucosal pertussis vaccine based on outer membrane vesicles (omvPV) is a promising candidate. Further, a vaccine that is stable outside the cold chain would be of substantial advantage for worldwide distribution and ... More
Dual Inhibition of PI3K/Akt and mTOR by the Dietary Antioxidant, Delphinidin, Ameliorates Psoriatic Features In Vitro and in an Imiquimod-Induced Psoriasis-Like Disease in Mice.

'The treatment of psoriasis remains elusive, underscoring the need for identifying novel disease targets and mechanism-based therapeutic approaches. We recently reported that the PI3K/Akt/mTOR pathway that is frequently deregulated in many malignancies is also clinically relevant for psoriasis. We also provided rationale for developing delphinidin (Del), a dietary antioxidant for ... More
Expanding biological activities of Ts19 Frag-II toxin: Insights into IL-17 production.
Tityus serrulatus (Ts) venom is composed of a mixture of toxins presenting diverse biological functions. However, although this venom has been studied over the past three decades, omics analysis revealed that most of its toxins are not identified or their biological activities are unknown. Ts19 Frag-II is included in this ... More

The bacterial ligase Sortase A (SA) and its mutated variants have become increasingly popular over the last years for post-translational protein modifications due to their unparalleled specificity and efficiency. The aim of this work was to study SA as a cross-linking enzyme for hydrogel-based tissue engineering. For this, we optimized ... More
GADD45ß plays a protective role in acute lung injury by regulating apoptosis in experimental sepsis in vivo.

Sepsis is a systemic inflammatory response syndrome due to microbial infection. Growth arrest and DNA-damage-inducible 45?beta (GADD45ß) are induced by genotoxic stress and inflammatory cytokines. However, the role of GADD45ß during bacterial infection remains unclear. This study was aimed at investigating the role of GADD45ß in sepsis. We used GADD45ß-knockout ... More

Graphene-based nanomaterials are increasingly engineered as components of biosensors, interfaces or drug delivery platforms in neuro-repair strategies. In these developments, the mostly used derivative of graphene is graphene oxide (GO). To tailor the safe development of GO nanosheets, we need to model ... More
Post-transplantation cyclophosphamide prevents graft-versus-host disease by inducing alloreactive T cell dysfunction and suppression.
Post-transplantation cyclophosphamide (PTCy) recently has had a marked impact on human allogeneic hematopoietic cell transplantation (HCT). Yet, our understanding of how PTCy prevents graft-versus-host disease (GVHD) largely has been extrapolated from major histocompatibility complex (MHC)-matched murine skin allografting models that were highly contextual in their efficacy. Herein, we developed a ... More
Global proteomic and functional analysis of Crotalus durissus collilineatus individual venom variation and its impact on envenoming.
Individual variations studies are important to understand the snakebite envenoming and to improve the antivenom production and its effectiveness. In this way, the objective of this study was a comparative analysis of intraspecific variation in the venom composition of 22 Crotalus durissus collilineatus specimens through proteomic techniques. Venoms were fractionated ... More
