Host acquired immunity is a critical factor that conditions the survival of parasites. Nevertheless, there is a shortage of data concerning inter-individual immunological inequalities in wild mammals. Sarcoptic mange is a widespread parasitosis that severely affects mammals such as the Iberian ibex (Capra pyrenaica). Despite some work on the subject, the immune response to sarcoptic mange infes...
Bimolecular fluorescence complementation was used to engineer CD8 molecules so that CD8αα and CD8αβ dimers can be independently visualized on the surface of a T cell during antigen recognition. Using this approach, we show that CD8αα is recruited to the immunological synapse almost as well as CD8αβ, but because the kinase Lck associates preferentially with CD8αβ in lipid rafts, CD8αα is the wea...
The model of membrane compartmentalization by self-organizing functional lipid microdomains, named lipid rafts, has been a fruitful concept resulting in great progress in understanding T cell signal transduction. However, due to recent results it has become clear that lipid rafts describe only one out of several membrane organizing principles crucial for T cell activation besides fences and pic...
HIV efficiently spreads in lymphocytes, likely through virological synapses (VSs). These cell-cell junctions share some characteristics with immunological synapses, but cellular proteins required for their constitution remain poorly characterized. We have examined here the role of ZAP-70, a key kinase regulating T-cell activation and immunological synapse formation, in HIV replication. In lymph...
Similarities in clinical course, age of onset, geographical distribution, and immunological responses of patients with schizophrenia and multiple sclerosis (MS) suggest that these two common illnesses of young adults may belong to a similar class of disorders. This review examines some of the similarities and differences between these two disorders and suggests that epidemiological, immunologic...
Worldwide 10 % of women in reproductive age and 25 up to 50 infertile are affected due endometriosis [1,2]. This condition has a comparable incidence asthma chronic low back pain [3]. The natural history the disease remains poorly understood although genetic, immunological, hormonal factors all believed contribute severity [4].
Background and purpose: Diabetes is a multifactorial disease in which genetic factors, environmental and immunological factors are involved in its pathogenesis. Due to the immunological role of blood groups, this study aimed to evaluate the distribution of ABO blood groups and Rh types in patients with type 2 diabetes in north of Iran. Materials and methods: This cross-sectional study was pe...
