Herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. During latent infection, virus genome exhibit limited transcription, with the HSV LATs consistently detected in latency infected ganaglia. Following ocular infection viral latency develops in the trigeminal ganglia. In this study PCR has been used for detection of HSV-1 nuc...

Background: Herpes simplex virus type-1 (HSV-1) establishes a lifelong latent infection in neurons following primary infection. The existence of latent HSV-1 DNA in the trigeminal ganglia of infected BALB/c mice was examined using a direct in situ PCR technique, based on Digoxigenin-11-dUTP detection system with anti-digoxigenin-peroxidase and 3,3'-diaminobenzidine (DAB) substrate. Methods: Eig...

Latent changes in trigeminal ganglion structure and function resembling inflammatory conditions may predispose to acute attacks of migraine pain. Here, we investigated whether, in trigeminal sensory ganglia, cytokines such as TNFα might contribute to a local inflammatory phenotype of a transgenic knock-in (KI) mouse model of familial hemiplegic migraine type-1 (FHM-1). To this end, macrophage o...

The results of this investigation reveal, for the first time, the presence of thymus-derived (T) lymphocytes in the trigeminal ganglia of rabbits undergoing primary corneal infection with herpes simplex virus type 1. Infiltration of T cells into the trigeminal ganglion was evident at 15 days after primary ocular infection but these cells were no longer present by 45 days after infection. Cornea...

The fifth and greatest cranial nerve, the trigeminal nerve (V), is in charge of detecting sensory inputs that come from craniofacial region. ganglia house cell bodies three branches nerve: ophthalmic (V1), maxillary (V2), mandibular (V3). These connect to second-order neurons brainstem nuclear complex. Trigeminal neuralgia one most prevalent types facial discomfort. characterized by abrupt, fle...

Herpes simplex virus type-1 latency and CD8+ T-cell occurrence were investigated in the trigeminal, geniculate, and vestibular ganglia from seven deceased humans. The HSV-1 "latency-associated transcript" was assessed by in situ hybridization and quantitative RT-PCR. Infiltration of CD8+ T cell was detected by immunohistochemistry and quantitative RT-PCR. The data show that HSV-1 latency and CD...

Ganglia are nodular structures in the peripheral nervous system (PNS) that formed by a cluster of neuron somas. They have important roles communicating signals from organs to and work as unique structure PNS. As great advances neuronal manipulation recording techniques been made, an increasing amount research is focused on function ganglia. However, ganglion surgery still very challenging, part...

The coexistence of the neuropeptides substance P, calcitonin gene-related peptide, galanin, somatostatin and neuropeptide Y with glucocorticoid receptors was studied in neurons of the rat lumbar dorsal root and trigeminal ganglia by means of the double immunofluorescence technique. Based on analysis of microphotographs, about one-third of the populations of nerve cells (small and large) contain...

Peripheral neuropathy is the most frequent neurologic complication associated with human immunodeficiency virus (HIV) infection, yet its pathogenesis remains poorly understood. To study the mechanisms causing HIV-induced peripheral nervous system disease, we examined trigeminal ganglia obtained from simian immunodeficiency virus (SIV)-inoculated macaques. SIV-infected macaques developed multifo...
