C-X-C chemokine receptor type 4 (انگلیسی: گیرندهٔ نوع ۴ کموکین سی-ایکس-سی) یا «CD184»، یک پروتئین است که انسان توسط ژن «CXCR4» کدگذاری می‌شود.^[۴]^[۵]

این پروتئین نوعی گیرندهٔ آلفا-کموکین اختصاصی برای مولکول پروتئینی SDF1 است که خاصیت کموتاکتیک قوی در جذب لنفوسیت‌ها دارد. SDF1 همچنین در لانه‌گزینی سلول‌های بنیادی خونساز در مغز استخوان نقش مهمی دارد. این پروتئین همچنین بیان ژنی CD20 را در لنفوسیت‌های بی تنظیم می‌کند.^[۶]

CXCR4 یکی از چند گیرندهٔ کموکین است که ویروس اچ‌آی‌وی جهت آلوده‌ساختنِ لنفوسیت‌های تی CD4+ از آنها استفاده می‌کند.

داروهای مسدودکنندهٔ این گیرنده قادرند سلول‌های بنیادی خونساز را به‌تحرک وادارند.

ثابت شده که مواجههٔ طولانی‌مدت با تتراهیدروکانابینول بیان CXCR4 را بر سطح لنفوسیت‌های تی CD4+ و CD8+ در میمون رزوس افزایش می‌دهد.^[۷]
