Cancer cells and virus-infected body cells can be killed before activation of adaptive immunity by ________.

Question

Quizplus · Accepted Answer

Natural killer cells are specialized cells of innate immunity which can recognize and kill cancer cells and virus-infected cells without activation of adaptive immunity such as T and B lymphocytes. T and B lymphocytes require activation by antigen-presenting cells and often take several days to mount an effective response. Pinocytosis is a process of taking up liquid or small particles by cells and is not directly involved in killing cancer or virus-infected cells.
