In a model of Candida albicans infection, blockade of Dectin-2 did not affect innate immune resistance but abrogated Candida -specific T cell production of IL-17 and, in combination with the absence of Dectin-1, decreased Th1 responses to the organism.

WebNov 17, 2024 · Abstract We show that a non-Hermitian two coupled Sachdev-Ye-Kitaev (SYK) model can provide thermodynamic structure equivalent to a Hermitian two coupled SYK model. The energy spectrum, the entanglement degree of the ground states and the low energy effective action of this model are not influenced by the non-Hermiticity. WebThe original SYK model involved Majorana fermions which did not carry any charge. In [12], a generalized SYK model with Dirac fermions with a global U(1) was introduced. At the strong coupling xed point, this U(1) symmetry is enhanced to local U(1) trans-formations.3 As in the uncharged case, the theory is singular at the strong coupling limit.
