Research lines

Our group examines the neurobiology of peripheral and spinal systems that regulate transmission of nociceptive information. Our laboratory is interested in the trigger mechanisms of pain at peripheral and central levels. Moreover, our laboratory is interested in studying the mechanisms which drive hyperalgesia and allodynia in several preclinic pain models (inflammatory, neuropathic and dysfunctional). Lab approaches include behavioral analysis of pain, as well as molecular biology (Western-blot and qPCR), histology (immunohistochemistry) and ELISA.

Relevant discoveries related with these research lines

1) Our findings suggest that diabetic pain is related to the generation of methylglyoxal which then activate the stress integrated response to induce pain.

2) Our findings suggest that aGABAA receptors could be a target to develop safer and effective analgesic in women.

3) Our data indicate that viruses, besides infection, induce pain through production of type 1 interferon.

4) We have developed models of pain related with prediabetes and diabetes. These models are useful to understand diabetic pain.

Current projects

1) Participation of spinal a6 GABAA receptors in neuropathic pain in rodents.
2) Study of the dopaminergic system in a fibromyalgia-type pain in rats.
3) Involvement of toll type receptors (TLR2, TLR4, TLR5 and RAGE) in several models of fibromyalgia in rats.
4) Pharmacological activity of cannabidiol on PPARg and GPR55 receptors in a model of neuropathic pain in mice.
5) Study of the thioctic acid’s mechanism of action on methylglyoxal-induced pain in mice.
