혈소판 계수 4
Platelet factor 4
Platelet factor 4 (PF4) is a small cytokine belonging to the CXC chemokine family that is also known as chemokine (C-X-C motif) ligand 4 (CXCL4) . This chemokine is released from alpha-granules of activated platelets during platelet aggregation, and promotes blood coagulation by moderating the effects of heparin-like molecules.이러한 역할들로 인해 상처 치료와 염증 치료에도 역할을 할 것으로 예상된다.[5]그것은 보통 프로토글리칸이 있는 콤플렉스에서 발견된다.
게노믹스
인간 PF4의 유전자는 인간 4번 염색체에 위치한다.[6]
함수
혈소판 인자-4는 70아미노산 단백질로 활성 혈소판의 알파그란룰에서 방출되며 헤파린에 높은 친화력으로 결합된다.주요 생리학적 역할은 혈관의 내피 표면에서 헤파린 유사 분자를 중화시켜 국소 안티트롬빈 활동을 억제하고 응고를 촉진하는 것으로 보인다.PF4는 중성미자와 섬유소용 강한 화학 반응제로서 염증과 상처 치료의 역할을 하고 있을 것이다.[5][7]
PF4는 중성미자, 섬유블라스트, 단세포에 대해 화학적이며, CXCR3-B로 알려진 케모카인 수용체 CXCR3의 스플라이스 변종과 상호작용한다.[8]
임상적 유의성
헤파린:PF4 콤플렉스는 헤파린 유도 혈소판감소증 내 항원으로, 항응고제 헤파린 투여에 대한 특이적 자가면역반응이다.[9]또한 PF4 자동항암제는 혈전증 환자에서 발견되었으며, HIT와 유사한 특징을 가지고 있으나 헤파린을 투여하지 않은 환자에서도 발견되었다.[10]PF4에 대한 항체는 옥스포드-아스트라제네카 또는 얀센 COVID-19 백신 접종에 따른 혈전증 및 혈전소판감소증의 경우에 관련되어 있다.[11][12]이 현상은 백신으로 인한 면역 혈전혈소판감소증(VITT)이라고 불린다.[13]PF4의 표현방식의 변화는 긴 COVID의 증상과도 관련이 있다.[14]
전신 경화증 환자에서 증가하여 또한 간성 폐질환이 있다.[15]
인간 혈소판 인자 4는 기생충의 소화액 vacuole을 선택적으로 침으로써 적혈구 내 말라리아 기생충을 죽인다.[16]
