[Abstract] In this review paper, we introduce recent progress in theoretical immunology, especially focusing on studies toward quantitative experiments for cell population growth and their mathematical models. We also show that, among mathematical models which have been independently developed by different authors, there exist similarities in terms of mathematical structure and underlying implicit assumptions.
