Molecular tug of war reveals adaptive potential of an immune cell repertoire [PDF]

open access: yesarXiv, 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 biological activity of soluble antigen-antibody complexes: II. Physical properties of soluble complexes having skin-irritating activity [PDF]

open access: yes, 1959
Previous work by Germuth and McKinnon (1), Trapani et al. (2), and ourselves (3) has established the fact that soluble antigen-antibody complexes formed in excess antigen can, (a) induce symptoms similar to anaphylaxis, (b) cause contraction of isolated ...

Engineering of an Avidity-Optimized CD19-Specific Parallel Chimeric Antigen Receptor That Delivers Dual CD28 and 4-1BB Co-Stimulation

open access: yesFrontiers in Immunology, 2022
Co-stimulation is critical to the function of chimeric antigen receptor (CAR) T-cells. Previously, we demonstrated that dual co-stimulation can be effectively harnessed by a parallel (p)CAR architecture in which a CD28-containing second generation CAR is

The effects of symmetry on the dynamics of antigenic variation [PDF]

open access: yesJ. 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 ...

Nanobody based dual specific CARs [PDF]

open access: yes, 2018
Recent clinical trials have shown that adoptive chimeric antigen receptor (CAR) T cell therapy is a very potent and possibly curative option in the treatment of B cell leukemias and lymphomas.

Antigen-presenting cells and antigen presentation in tertiary lymphoid organs [PDF]

open access: yes, 2016
Tertiary lymphoid organs (TLOs) form in territorialized niches of peripheral tissues characterized by the presence of antigens; however, little is known about mechanism(s) of antigen handling by ectopic lymphoid structures.
