In vitro culture systems using bone marrow cells from BALB/C mice were set up in medium supplemented with spleen-derived medium. Bone marrow cells grown in spleen-derived medium gave rise to cultures containing >97% mast cells. The cells were used in polarisation chemotaxis assays with the intention of determining the effect of nerve tissue-derived neurotransmitters on mast cell migration. ...

Abstract There may be immunologic alternations during Tourette syndrome (TS) development. This study aimed to determine the immune function changes in different aspects (spleen or thymus index, plasma cytokines, and T cell) an 3,3′‐iminodipropionitrile (IDPN)‐induced rat model of TS. Male Sprague‐Dawley rats were assigned control TS groups. The group received intraperitoneal infections normal s...

Background: Autoimmune type 1 diabetes mellitus is caused by T-cell mediated immune destruction of the insulin-producing β-cell in pancreatic islets of Langerhans. Specificity of the auto-antibodies and of the auto-reactive T-cells has been investigated, in which several auto-antigens were proposed. Objective: To determine whether glutamic acid decarboxylase (GAD) feeding would induce oral tol...

The spleen has a combined function of immune defence and quality control of senescent or altered red cells. It is the first organ injured in sickle cell anaemia (SCA) with evidence of hyposplenism present before 12 months in the majority of children. Repeated splenic vaso-occlusion leads to fibrosis and progressive atrophy of the organ (autosplenectomy), which is generally complete by 5 years i...

Introduction: Based on human studies, inequality and social injustice have adverse effects on the individual and community health. In this study, the effects of food intake inequality and social status changes on pain perception and immunological factors were investigated in Balb/C mice. Methods: The present study was conducted by implementing different social stresses including food depriva...

A purification procedure of pertussis toxin (PT) from submerged culture of Bordetella pertussis (B.pertussis) strain 134 using adsorption and affinity chromatography was discussed. The yield of the resulting PT was approximately 37.5mg/l of concentrated culture supernatant. The polypeptide pattern of the purified PT was investigated by SDS-PAGE and showed five bands between 11 to 26 KDa using l...
