Regulation of T cell expansion by antigen presentation dynamics [PDF]
PNAS 2019, 116 (13) 5914-5919, 2018 An essential feature of the adaptive immune system is the proliferation of antigen-specific lymphocytes during an immune reaction to form a large pool of effector cells. This proliferation must be regulated to ensure an effective response to infection while avoiding immunopathology.

Disease Markers, 2018 Purpose The prognostic role of serum cancer antigen 15-3 (CA15-3) and carcinoembryonic antigen (CEA) in breast cancer remains controversial. In this study, we conducted a meta-analysis to investigate the prognostic value of these two markers in breast ...

Cancer Science, 2018 Human carcinoembryonic antigen (CEA) is the prototypic member of a family of highly related cell surface glycoproteins that includes carcinoembryonic antigen‐related cell adhesion molecule 6 (CEACAM6) and others.

Molecular tug of war reveals adaptive potential of an immune cell repertoire [PDF]
arXiv, 2022 The adaptive immune system constantly remodels its lymphocyte repertoire for better protection against future pathogens. Its ability to improve antigen recognition on the fly relies on somatic mutation and selective expansion of B lymphocytes expressing high-affinity antigen receptors.

The effects of symmetry on the dynamics of antigenic variation [PDF]
J. Math. Biol. 66, 115-137 (2013), 2012 In the studies of dynamics of pathogens and their interactions with a host immune system, an important role is played by the structure of antigenic variants associated with a pathogen. Using the example of a model of antigenic variation in malaria, we show how many of the observed dynamical regimes can be explained in terms of the symmetry of ...

Characteristics of carcinoembryonic antigen-producing colorectal cancers: A population based study [PDF]
Archive of Oncology, 2019 Objectives: Serum carcinoembryonic antigen is a tumor marker often found to be elevated in colorectal cancer patients. Elevated carcinoembryonic antigen has been strongly associated with poor prognosis.

Cancer Medicine, 2018 Tissue carcinoembryonic antigen (t‐CEA) and serum carcinoembryonic antigen (s‐CEA) expression profiles are the most useful tumor markers for the diagnosis and evaluation of colorectal cancer (CRC) worldwide; however, their roles in CRC progression remain
