The Mitsuda reaction, a delayed granulomatous skin reaction elicited by the intradermal injection of heat-killed Mycobacterium leprae, is an in vivo test reflecting the ability to generate an immune granuloma after sensitization by diverse mycobacterial infections. Accumulating evidence for the genetic control of the Mitsuda reaction has been reported. We performed a genomewide linkage scan for the quantitative Mitsuda reaction in 19 large families from Vietnam with a history of leprosy (114 offspring). Suggestive linkage was found at chromosomal regions 2q35 (P = 9 x 10(-4) at the SLC11A1 locus) and 17q21-25 (P = 8 x 10(-4)). Interestingly, these 2 regions have been previously linked to mycobacterial infection and other granulomatous diseases.

Article Synopsis
- Intratumoral immune profiles play a crucial role in determining prognosis and treatment effectiveness, potentially leading to personalized treatments using specific biomarkers.
- A new 6-marker rapid multiplex immunohistochemistry (IHC) method was created, streamlining the process originally based on a 14-marker system, making it faster and less complex.
- Validation studies demonstrated that this new method reliably assessed immune features and densities in cancer tissues, which could improve the way we understand and treat tumors clinically.

Department of Laboratory Medicine, Osaka Women's and Children's Hospital, Izumi 594-1101, Japan.
Article Synopsis
- In newborn screening (NBS), integrating multiplex assays can enhance the detection of new target diseases, such as severe primary immunodeficiency (PID) and spinal muscular atrophy (SMA).
- Recent advancements in testing technology, like the use of quantitative real-time polymerase chain reaction (qPCR), allow simultaneous screening for these conditions, improving early diagnosis and treatment.
- In Osaka, Japan, a multiplex TaqMan qPCR assay was successfully implemented, identifying cases of PID and SMA among over 105,000 newborns, showcasing its effectiveness in large-scale NBS programs.
Biosimilar(BS)drugs have recently been introduced owing to concerns with healthcare economics. In this report, we present a case in which a patient discontinued bevacizumab treatment following an allergic reaction to a BS formulation of bevacizumab but was able to safely continue treatment by switching to an original bevacizumab formulation in the late-line setting. The patient was a 66-year-old man diagnosed with unresectable colorectal cancer with synchronous multiple liver metastases.

Beneficial Bacillus subtilis (BS) symbiosis could combat root pathogenesis, but it relies on root-secreted sugars. Understanding the molecular control of sugar flux during colonization would benefit biocontrol applications. The SWEET (Sugar Will Eventually Be Exported Transporter) uniporter regulates microbe-induced sugar secretion from roots; thus, its homologs may modulate sugar distribution upon BS colonization.
