Abstract::
According to the World Health Organization (WHO), diabetes has been increasing
steadily over the past few decades. In developing countries, it is the cause of increased morbidity
and mortality. Diabetes and its complications are associated with education, occupation, and
income across all levels of socioeconomic status. Factors, such as hyperglycemia, social ignorance,
lack of proper health knowledge, and late access to medical care, can worsen diabetic
complications. Amongst the complications, neuropathic pain and inflammation are considered
the most common causes of morbidity for common populations. This review is focused on exploring
protein kinase C (PKC)-mediated TGF-β regulation in diabetic complications with particular
emphasis on allodynia. The role of PKC-triggered TGF-β in diabetic neuropathy is not
well explored. This review will provide a better understanding of the PKC-mediated TGF-β
regulation in diabetic neuropathy with several schematic illustrations. Neuroinflammation and
associated hyperalgesia and allodynia during microvascular complications in diabetes are scientifically
illustrated in this review. It is hoped that this review will facilitate biomedical scientists
to better understand the etiology and target drugs effectively to manage diabetes and diabetic
neuropathy.
