Oral tolerance induction with altered forms of ovalbumin

Brazilian Journal of Medical and Biological Research, 1998
As a T cell-dependent phenomenon, oral tolerance is not expected to depend necessarily on native configuration of antigens. We investigated the induction of oral tolerance with modified ovalbumin (Ova).

Melatonin Modifies Histone Acetylation during In Vitro Maturation of Mouse Oocytes

Cell Journal, 2018
Objective We evaluated the effect of melatonin, as a potent antioxidant agent, on glutathione (GSH) and reactive oxygen species (ROS) levels, as well as histone H3 lysine 9 (H3K9), and H4 lysine 12 (H4K12) acetylation when added to oocytes culture ...

(C57BL/6J×DBA/2J) F1 mice display an intermediate phenotype after infection with Influenza A virus and DBA/2NHsd exhibit the same susceptibility as DBA/2J.

, 2013
C57BL/6J, DBA/2J, DBA/2NHsd and (C57BL/6J×DBA/2J) F1 (labeled B6D2F1 in the figure) mice were infected intra-nasally with 2×103 FFU PR8 virus. Weight loss and survival of infected mice was followed over a period of 14 days.

Expression of costimulatory molecules in antigen-activated peritoneal macrophages treated with either ovalbumin or palmitoyl-ova conjugates

Brazilian Archives of Biology and Technology, 2013
One of the mechanisms by which adjuvants are believed to promote T-cell activation and prevent induction of oral tolerance is by up-regulating the expression of co-stimulatory molecules on antigen presenting cells.

Increased intestinal permeability and tight junction disruption by altered expression and localization of occludin in a murine graft versus host disease model

BMC Gastroenterology, 2011
Background Hematopoietic stem cell transplantation is increasingly performed for hematologic diseases. As a major side effect, acute graft versus host disease (GvHD) with serious gastrointestinal symptoms including diarrhea, gastrointestinal bleeding and

Murine susceptibility to Chagas' disease maps to chromosomes 5 and 17

, 2003
Chagas' disease is caused by the protozoan parasite Trypanosoma cruzi and commonly modelled in inbred mice. Susceptibility of mouse strains to experimental infection varies considerably.

The C-terminal domain of Emi2 conjugated to cell-penetrating peptide activates mouse oocyte

Frontiers in Cell and Developmental Biology
IntroductionThe cell cycle of ovulated oocytes from various animal species, including mice, arrests at the second meiotic metaphase until fertilization. The meiotic cell cycle must be initiated to initiate embryonic development.
