Depletion of Invariant NKT Cells Reduces Inflammation-Induced Preterm Delivery in Mice

Inflammation-Induced Preterm Delivery in Depletion of Invariant NKT Cells Reduces

NK, NKT and Invariant-NKT Cells in Tumor Draining Lymph Nodes of Patients with Breast Cancer

Background: NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. Objective: To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLN...

Invariant NKT cells

Although invariant natural killer T (iNKT) cells influence antitumor responses indirectly by secreting cytokines and promoting the cytolytic functions of T and NK cells, we find that iNKT cells mediate direct tumoricidal activity in vitro and significantly inhibit tumor growth in vivo, even in the absence of other cytotoxic lymphocytes.

Invariant NKT cells are required for airway inflammation induced by environmental antigens

Invariant NKT cells (iNKT cells) are a unique subset of T lymphocytes that rapidly carry out effector functions. In this study, we report that a majority of sterile house dust extracts (HDEs) tested contained antigens capable of activating mouse and human iNKT cells. HDEs had adjuvant-like properties in an ovalbumin (OVA)-induced asthma model, which were dependent on Vα14i NKT cells, as vaccina...
