  Coxsackie B4 virus
Coxsackie B4 virus is a virus which can trigger an autoimmune reaction[?] which results in an attack on the beta cells.
There are several viruses in the Coxsackie family and many of them seem to evoke this response, as do several other agents.
A genetic predispostion to this seems to be required.

  Diabetes induced by Coxsackie virus: Initiation by bystander damage and not molecular mimicry - Nature Medicine
Coxsackie B4 virus is strongly associated with the development of insulin-dependent diabetes mellitus in humans and shares sequence similarity with the islet autoantigen glutamic acid decarboxylase.
We infected different strains of mice with Coxsackie B4 virus to discriminate between the two possible induction mechanisms, and found that mice with susceptible MHC alleles had no viral acceleration of diabetes, but mice with a T cell receptor transgene specific for a different islet autoantigen rapidly developed diabetes.
These results show that diabetes induced by Coxsackie virus infection is a direct result of local infection leading to inflammation, tissue damage, and the release of sequestered islet antigen resulting in the re-stimulation of resting autoreactive T cells, further indicating that the islet antigen sensitization is an indirect consequence of the viral infection.

Yoon and Co-workers[9] isolated Coxsackie B4 virus from the pancreas of a boy with acute diabetes mellitus.
The serological evidence Coxsaekie B virus infections in acute pancreatitis patients as reported by other workers,[1],[6],[8] ranged from 5.2% to 90.9%, with an initial testing dilutions ranging from to 1 : 32.Hence, wide variations in positivity rate of Coxsaekie B virus infections may be partly due to the differences in the testing dilutions.
Whether the Coxsackie B viruses have any etiological association with the genesis of pancreatitis is yet to be studied in detail including the animal experiments using viruses isolated from the pancreatic specimens of the patients.

 Defeat Diabetes: Key Findings: Diabetes Is Caused By A Virus
The candidate virus that the research team focused on was the Coxsackie B4 virus (CVB4), a bug that causes typical viral symptoms and most commonly found in children.
Using the genetic code of the virus and the latest DNA technology, the Action Researchers were able to grow key parts of the virus and see how the body responds to these, using blood samples of some 40 Type 1 diabetics: teenagers and young adults who had been diagnosed within the last five months.
Dr Peakman, says: ‘A virus is like an enemy invasion that the body fights with using an ‘infantry’ of anti-viral cells called effector cells, that counteract the virus.

Interestingly, the tropism of the virus was altered in SOCS-1 transgenic (Tg) mice, and CVB3 was detected in islet cells of SOCS-1-Tg mice before [beta]-cell loss and the onset of diabetes.
One example is when the infecting virus causes direct cytolysis of [beta]-cells, which leads to their destruction and diabetes in the infected host (2,3).
In the present study, MCMV served as a model virus for HCMV, with the aim to test whether CMV tropism for the [beta]-cell is regulated by IFNs.
