The authors studied the left kidney consequences of splenic irradiation in 40 patients with lymphomas. The renal work-up performed before irradiation and every six months afterwards includes : blood pressure, biological tests, IVP and 197 Hg Neohydrine renal scan. Computer scan data processing showed a partial disfunction of left kidney in 16 patients with 18 month-follow up. Renal disfunction appeared within 8 to 10 months following spleen irradiation. During that period no clinical or radiological abnormalities were observed.

Fitness costs of Mycobacterium tuberculosis resistant to rifampicin is compensated by rapid Th2 polarization mediated by early and high IL-4 production during mice infection.

It was a general belief that drug resistance in Mycobacterium tuberculosis (Mtb) was associated with lesser virulence, particularly rifampicin resistance, which is usually produced by mutations in the RNA polymerase Beta subunit (RpoB). Interestingly, this kind of bacterial mutations affect gene transcription with significant effects on bacterial physiology and metabolism, affecting also the bacterial antigenic constitution that in consequence can produce diverse immune responses and disease outcome. In the present study, we show the results of the Mtb clinical isolate A96, which is resistant to rifampicin and when used to infect BALB/c mice showed hypervirulence, apparently by rapidly polarization of the Th2 immune response through early and high production of IL-4.

Patients with a traumatic brain injury (TBI) are susceptible to hospital-acquired infections, presenting a significant challenge to an already-compromised immune system. The consequences and mechanisms by which this dual insult worsens outcomes are poorly understood. This study aimed to explore how a systemic immune stimulus (lipopolysaccharide, LPS) influences outcomes following experimental TBI in young adult mice.

Introduction: Wound healing causes heavy economic burdens for families and society, becoming a critical issue in the global healthcare system. While the role of immune cells in the wound healing process is well-established, the involvement of B cells remains poorly understood. This study aims to elucidate the essentiality of B cells in wound repair.

With the rapid development of immunotherapy in recent years, cytokine storm has been recognized as a common adverse effect of immunotherapy. The emergence of COVID-19 has renewed global attention to it. The cytokine storm's inflammatory response results in infiltration of large amounts of monocytes/macrophages in the lungs, heart, spleen, lymph nodes, and kidneys.
