Significant increase in MIC-A and MIC-B and soluble MIC-A and MIC-B in canine lymphomas.

Non-Hodkin's lymphoma (NHL) is the most frequent hematologic malignancy in humans and dogs. NKG2D is one of the most critical receptors on NK cells, recognizing their natural ligands on malignant cells such as A and B major histocompatibility complex-related proteins (MIC-A and MIC-B). Soluble molecules (sMIC-A and sMIC-B) can interfere with immune synapsis between NK cells and tumor cells, impeding NK cytotoxicity.

[Two clinical cases of sporadic lymphangioleiomyomatosis].

Lymphangioleiomyomatosis (LAM) is a rare lung disease of unknown etiology, described since 1918 associated with tuberous sclerosis complex (TSC-LAM) and are reported sporadically (S-LAM). It is classified within the group of interstitial lung diseases (ILD) and currently the European Respiratory Society (ERS) has published guidelines for diagnosis and treatment. The objective is to evaluate the clinical presentation of two patients, evolution, management, and review of current treatment.
