쿠자와 준지 교수의 연구실은 당뇨병의 병태생리학적 기전을 규명하기 위해 췌장 β세포 기능 저하, 임상적 인슐린 분비 기능, 그리고 비만과 관련된 비정상적인 지방 축적(특히 췌장 및 심장 등 기관 내 지방 축적)에 중점을 두고 있습니다. 특히 췌장 지방 축적, 이소프레서의 염증 반응, β세포 기능 저하와 당뇨병 진행 간의 연관성에 대한 기초 및 임상 연구를 진행하고 있습니다. 이는 당뇨병의 조기 진단 및 개인 맞춤형 치료 전략 개발에 기여할 수 있습니다.

Insulin secretion evaluated by F-CPR, CPI, I.I., U-CPR and the duration of type 2 diabetes were useful parameters for predicting the efficacy of liraglutide in patients with type 2 diabetes. (J Diabetes Invest, doi: 10.1111/j.2040-1124.2011.00168.x, 2011).
Type 2 diabetes patients had high LD accumulation in β cells, which was associated with insulin resistance, hyperglycemia, aging and β cell dysfunction involving decreased mature insulin granules.
In type 2 diabetes patients, pancreatic fat was less associated with obesity-related indicators than liver fat, but was more strongly associated with the longitudinal decrease in endogenous insulin-secreting capacity.
The inflammation of islets is associated with pancreatic fatty infiltration and hyperglycemia, which may further aggravate glucose tolerance.
The pancreatic α/β increases after type 2 diabetes onset and correlates with diabetes duration. This change might occur through α-cell proliferation and phenotypic changes in pancreatic endocrine cells.
Ectopic fat is found in liver, muscle, and kidney and is known to accumulate as visceral fat. In recent years, ectopic fat has also been observed in the pancreas, and it has been said that pancreatic fat accumulation is related to the pathophysiology of diabetes and the onset of diabetes, but the relationship has not yet been determined. In the heart, epicardium fat is another ectopic fat, which is associated with the development of coronary artery disease. Ectopic fat is also observed in the my
Immune checkpoint inhibitors (ICIs) could cause type 1 diabetes (T1D). However, the underlying mechanism remains unclear. We immunohistochemically analyzed pancreatic specimens from three individuals with ICI-related T1D, and their histopathological data were compared those from three patients who had received ICI therapy but did not develop T1D (non-T1D) and seven normal glucose-tolerant subjects as control subjects. All ICI-related T1D patients had susceptible HLA haplotypes. In ICI-related T1
Insulin sensitizers were effective in type 2 diabetic patients with high insulin resistance estimated by the ITT. The ITT could be useful to predict the effectiveness of insulin sensitizers.
These results indicate that HB-EGF gene transduction into adult pancreatic duct cells not only promotes the proliferation of pre-existing beta cells but also leads to beta-cell differentiation from duct cells, and the resulting increase in beta-cell mass improves glucose tolerance.
Postprandial glucagon secretion was shown to be dysregulated in patients with type 2 diabetes. However, the differences in secretory patterns between obese and non-obese patients and their physiological effects on plasma glucose levels are not fully understood. This study population consisted of 21 (10 obese and 11 non-obese) consecutive patients with type 2 diabetes admitted for glycemic control. A 3-hour mixed-meal tolerance test was performed after glycemic control improved. Six non-diabetic
