A novel microtubule de-stabilizing complementarity-determining region C36L1 peptide displays antitumor activity against melanoma in vitro and in vivo

2015

AbstractShort peptide sequences from complementarity-determining regions (CDRs) of different immunoglobulins may exert anti-infective, immunomodulatory and antitumor activities regardless of the specificity of the original monoclonal antibody (mAb). In this sense, they resemble early molecules of innate immunity. C36L1 was identified as a bioactive light-chain CDR1 peptide by screening 19 conserved CDR sequences targeting murine B16F10-Nex2 melanoma. The 17-amino acid peptide is readily taken up by melanoma cells and acts on microtubules causing depolymerization, stress of the endoplasmic reticulum and intrinsic apoptosis. At low concentrations, C36L1 inhibited migration, invasion and proli…

Mast cells as protectors of health.

2019

Mast cells (MCs), which are well known for their effector functions in T(H)2-skewed allergic and also autoimmune inflammation, have become increasingly acknowledged for their role in protection of health. It is now clear that they are also key modulators of immune responses at interface organs, such as the skin or gut. MCs can prime tissues for adequate inflammatory responses and cooperate with dendritic cells in T-cell activation. They also regulate harmful immune responses in trauma and help to successfully orchestrate pregnancy. This review focuses on the beneficial effects of MCs on tissue homeostasis and elimination of toxins or venoms. MCs can enhance pathogen clearance in many bacter…

Vacunas y evolución: ¿Por qué es importante entender la diversidad genética de los patógenos?

2013

Desde el punto de vista de las intervenciones en salud pública no hay mejor arma que aquella que permite prevenir la transmisión o aparición de la enfermedad. Dentro del campo de las enfermedades infecciosas las vacunas se han convertido en esa arma y han permitido controlar muchas de ellas. Hoy en día hay un gran número de enfermedades infecciosas emergentes para las que no existen vacunas o enfermedades olvidadas que están reemergiendo. Nuevas vacunas se están desarrollando para atacar a los patógenos que están relacionados con ellas. Sin embargo, y a pesar de la importancia del diseño de una buena vacuna, la diversidad genética de los patógenos no se ha tenido siempre en cuenta. El estud…
