Description

백혈구의 혈관외유출 억제 활성 및 비만세포 탈과립 억제 활성을 갖는 펩타이드를 포함하는 약학 조성물{Pharmaceutical composition comprising peptide having inhibitory activities against transendothelial migration of leucocytes and degranulation of mast cells}Pharmaceutical composition comprising peptide having inhibitory activities against transendothelial migration of leucocytes and degranulation of mast cells}

본 발명은 allergin-1에서 유래한 펩타이드 단편(peptide fragment 또는 small peptide)을 포함하는 염증 질환 또는 알레르기의 예방 또는 치료용 약학 조성물에 관한 것이다. 상기 펩타이드는 백혈구의 혈관외유출 억제 활성 및 비만세포 탈과립 억제 활성을 갖는다.The present invention relates to a pharmaceutical composition for preventing or treating an inflammatory disease or allergy, including a peptide fragment (small peptide or small peptide) derived from allergin-1. The peptide has an extravasation inhibitory activity and leukocyte degranulation inhibitory activity of leukocytes.

감염, 외상 등에 의해 손상된 조직의 구조와 기능을 복원하기 위한 생체의 방어 반응을 통칭하여 염증 반응이라 한다. 염증 부위로의 백혈구 세포의 이동(mobilization)은 감염에 대한 신속한 해결(resolution) 및 다양한 외상으로부터 발생하는 조직 손상을 복구하는데 중요하다. 그러나, 잘못되거나 지속적인 염증 반응은 인체 조직의 손상과 질환을 야기한다. 예를 들어, 염증 질환은 뇌척수막염, 장염, 피부염, 포도막염, 뇌염, 성인성 호흡곤란 증후군 등과 같이 세균이나 바이러스에 의한 감염이나, 외상, 자가면역질환과 장기이식 거부 등과 같은 비감염 요인에 의하여 발생한다. 염증 질환은 증상이나 병리학적 특징이 구분되는 급성 및 만성 염증 질환으로 분류된다. 알레르기나 세균과 바이러스의 감염과 같은 급성 염증의 국소적 증상은 혈류 및 혈관 크기의 변화, 혈관 투과성의 변화 및 백혈구의 침윤 등으로 나타난다. 이에 반하여 류마티스 관절염, 죽상 동맥경화증. 만성 신장염, 간경화증 등을 비롯한 만성 염증의 주요 병리학적 특징은 염증 유발 요인이 제거가 되지 않아 염증부위로 단핵구, 호중구, 림프구, 형질세포들이 지속적으로 침윤하는 것으로, 그 결과 염증 반응이 만성화된다.The protective response of the living body to restore the structure and function of tissues damaged by infection, trauma, etc. are collectively called an inflammatory response. Mobilization of leukocytes to the site of inflammation is important for rapid resolution of infection and repairing tissue damage resulting from various traumas. However, faulty or persistent inflammatory reactions cause damage and disease of human tissue. For example, inflammatory diseases are caused by bacterial or viral infections such as meningitis, enteritis, dermatitis, uveitis, encephalitis, adult respiratory distress syndrome, or non-infectious factors such as trauma, autoimmune diseases, and organ transplant rejection. Inflammatory diseases are classified into acute and chronic inflammatory diseases in which symptoms or pathological features are distinguished. Local symptoms of acute inflammation, such as allergies or bacterial and viral infections, are manifested by changes in blood flow and blood vessel size, changes in vascular permeability, and infiltration of white blood cells. In contrast, rheumatoid arthritis, atherosclerosis. The main pathological features of chronic inflammation, including chronic nephritis and cirrhosis, are the infiltration of monocytes, neutrophils, lymphocytes, and plasma cells into the site of inflammation, resulting in chronic inflammation.

염증 반응이 일어나기 위하여서는 백혈구의 염증 부위로의 침윤이 필수적이며, 이는 여러 세포 유착 분자들(cell adhesion molecules)이 관여하는 단계를 포함한다. 즉, 염증 부위에서 분비되는 케모카인(chemokine)의 유도에 의하여 염증부위의 혈관으로 이동한 백혈구들이 이동속도를 줄이면서 혈관 내피 세포 표면에서 회전하는 단계 (Rolling stage), 백혈구들이 회전을 멈추고 내피세포벽에 견고히 부착하는 단계 (Adhesion stage), 모세혈관과 바닥막을 침윤하는 단계 (Transmigration stage)로 구분할 수 있다. 상기 마지막 단계 즉 침윤하는 단계(Transmigration stage)는 혈구누출(diapedesis)로 지칭된다.Infiltration of leukocytes into the site of inflammation is essential for an inflammatory response to occur, which involves the involvement of several cell adhesion molecules. That is, the leukocytes moved to the blood vessels of the inflammation site by the induction of chemokine secreted from the inflammation site rotates on the surface of the vascular endothelial cells while reducing the movement speed, and the white blood cells stop the rotation and endothelial cell wall. It can be divided into an adhesion stage and a transmigration stage of infiltration of capillaries and bottom membranes. This last step, or transmigration stage, is called diapedesis.

한편, allergin-1은 면역글로불린-유사 수용체(immunoglobulin-like receptor)로서, 비만세포, 수지상세포나 대식세포와 같은 골수성 세포들에서 주로 발현되며 림프구에서는 발현이 되지 않는 것으로 알려져 있으며, 비만세포의 탈과립을 억제하는 기능을 함으로써, 즉시과민반응을 조절하는 데에 중요한 역할을 한다 (Hitomi K, Tahara-Hanaoka S, Someya S, Fujiki A, Tada H, Sugiyama T, Shibayama S, Shibuya K, Shibuya A. 2010. An immunoglobulin-like receptor, Allergin-1, inhibits immunoglobulin E-mediated immediate hypersensitivity reactions. Nat Immunol. 11:601).On the other hand, allergin-1 is an immunoglobulin-like receptor, which is mainly expressed in myeloid cells such as mast cells, dendritic cells or macrophages and is not known to be expressed in lymphocytes. Play an important role in regulating immediate hypersensitivity (Hitomi K, Tahara-Hanaoka S, Someya S, Fujiki A, Tada H, Sugiyama T, Shibayama S, Shibuya K, Shibuya A. 2010). An immunoglobulin-like receptor, Allergin-1, inhibits immunoglobulin E-mediated immediate hypersensitivity reactions. Nat Immunol. 11: 601).
