Coxsackievirus infection induces direct pancreatic β cell killing but poor antiviral CD8 T cell responses.

Coxsackievirus B (CVB) infection of pancreatic β cells is associated with β cell autoimmunity and type 1 diabetes. We investigated how CVB affects human β cells and anti-CVB T cell responses. β cells were efficiently infected by CVB in vitro, down-regulated human leukocyte antigen (HLA) class I, and presented few, selected HLA-bound viral peptides.

[Efficacy of Sildenafil oral spray for the treatment of erectile dysfunction in patients with type 2 diabetes mellitus and prediabetes].

Aim: To evaluate the results of using Sildenafil in the form of an oral spray (Gent) for the treatment of erectile dysfunction (ED) in men with type 2 diabetes mellitus (DM) and prediabetes.

Material And Methods: A total of 60 patients were divided into two groups of 30 people. The group 1 included patients with prediabetes, while group 2 consisted of patients with type 2 DM.

Coxsackievirus infection induces direct pancreatic β-cell killing but poor anti-viral CD8+ T-cell responses.

Coxsackievirus B (CVB) infection of pancreatic β cells is associated with β-cell autoimmunity. We investigated how CVB impacts human β cells and anti-CVB T-cell responses. β cells were efficiently infected by CVB , downregulated HLA Class I and presented few, selected HLA-bound viral peptides.

The PAX-FOXO1s trigger fast trans-differentiation of chick embryonic neural cells into alveolar rhabdomyosarcoma with tissue invasive properties limited by S phase entry inhibition.

The chromosome translocations generating PAX3-FOXO1 and PAX7-FOXO1 chimeric proteins are the primary hallmarks of the paediatric fusion-positive alveolar subtype of Rhabdomyosarcoma (FP-RMS). Despite the ability of these transcription factors to remodel chromatin landscapes and promote the expression of tumour driver genes, they only inefficiently promote malignant transformation in vivo. The reason for this is unclear.

Basics of CD8 T-cell immune responses after influenza infection and vaccination with inactivated or live attenuated influenza vaccine.

Introduction: One of the essential mechanisms of virus infection control is cell-mediated cytotoxicity, which can act in an antibody-dependent or -independent fashion and is provided by different effector cells. The role of CD8 T-cells in infection control and in affecting the pathological outcome of different types of infection has been demonstrated in numerous animal studies. Despite this, their role in controlling human influenza infection is not fully understood.
