CD40 ligand (CD40L), also known as CD154, is a protein that is primarily expressed on the surface of activated T cells and belongs to a member of the tumor necrosis factor superfamily. Lack of CD40L results in an inability to undergo immunoglobulin class switch and only class IgM antibodies can be generated. CD40L exists as a membrane-bound form with a molecular weight of 33 kDa and as a soluble form with a molecular weight of 18 kDa. Soluble CD40L (sCD40L) is stored in platelet granules and thus its presence in the blood is a biomarker of platelet activation. sCD40L expression is known to be upregulated in atheroma-associated cells.

Lignoceric acid has 24 carbons and no double bonds (24:0). It can be formed from behenic acid using the elongase enzyme. It is found in peanuts, nut and seed oils. It can also be found in wood tar. Lignoceric acid is one of many fatty acids which compose brain tissue and myelin.

Limosilactobacillus reuteri is a lactic acid bacterium that naturally resides in the gastrointestinal tract of humans and other animals. It is considered a probiotic due to its potential health benefits, particularly in gastrointestinal health. In the context of a GI test, the presence of Limosilactobacillus reuteri can indicate its role in maintaining gut health and its potential therapeutic effects.

Os linfócitos são um tipo de glóbulo branco essencial para a defesa imunológica. Eles ajudam o corpo a combater infecções, doenças e invasores estranhos. Como parte do sistema imunológico, os linfócitos trabalham em conjunto com gânglios linfáticos, tecidos e órgãos linfáticos para proteger contra ameaças.
Os linfócitos identificam e lembram antígenos (substâncias estranhas como bactérias, vírus e toxinas). Após o primeiro contato com um antígeno, alguns linfócitos se tornam células de memória, permitindo uma resposta mais rápida e eficaz em exposições futuras. Esse mecanismo é a base das vacinações.
Os linfócitos monitoram continuamente o corpo, interagindo com fagócitos (monócitos, macrófagos) e células dendríticas para coordenar a resposta imunológica.

Os linfócitos são um tipo de glóbulo branco que desempenha um papel essencial no seu sistema imunológico. Eles ajudam o corpo a combater doenças e infecções, identificando e atacando invasores nocivos como bactérias, vírus e toxinas. Como parte de uma rede complexa de células imunológicas, linfonodos, tecidos linfáticos e órgãos, os linfócitos são fundamentais para manter o sistema de defesa do corpo.
As células T regulam a resposta do sistema imunológico e atacam diretamente células infectadas ou cancerígenas.
As células B produzem anticorpos—proteínas que especificamente identificam e neutralizam vírus, bactérias e outras substâncias estranhas.
Diferentemente das células T, as células NK podem destruir células tumorais e infectadas sem a necessidade de ativação prévia, proporcionando uma resposta imune rápida.
Os linfócitos têm a capacidade única de memorizar antígenos, que são substâncias estranhas que desencadeiam uma reação imunológica. Após encontrar um antígeno, alguns linfócitos se transformam em células de memória. Essas células permitem que o sistema imunológico responda de forma mais rápida e eficaz quando exposto ao mesmo antígeno novamente. Este mecanismo é a base de como as vacinas protegem contra certas doenças.
Os linfócitos estão constantemente monitorando o corpo em busca de antígenos—desde um resfriado comum até células cancerígenas. Eles interagem com outras células imunológicas, como fagócitos (por exemplo, monócitos e macrófagos) e células especializadas, como as dendríticas, para coordenar uma resposta imune direcionada.
Os linfócitos são elementos-chave do sistema imunológico, trabalhando para detectar, responder e memorizar invasores nocivos. Eles garantem proteção de longo prazo e fortalecem a imunidade do corpo contra ameaças futuras.

Linoleic acid is by far the most abundant polyunsaturated fatty acid in most human tissues. Linoleic acid is an essential fatty acid, and low levels indicate dietary insufficiency.

Linoleic acid is by far the most abundant polyunsaturated fatty acid in most human tissues. Linoleic acid is an essential fatty acid, and low levels indicate dietary insufficiency.
Optimal range: 18.8 - 28.3 wt %
Linoleic acid (LA) is the only essential omega-6 fatty acid and must be obtained from the diet.
From LA, other omega-6s can be created using elongase and desaturase enzymes. LA contains 18 carbons, with 2 double bonds, the first of which is at the 6th carbon position (18:2n6).
LA is found in nuts and vegetable oils (corn, soybean, canola, sunflower, etc.) as well as most meats. When the double bonds of LA are arranged differently, the term conjugated LA (CLA) is used. Although technically CLA can be termed a trans-fat, a natural type of CLA can be obtained in the dietary intake of meat and milk from ruminant animals. There are many isomers of CLA – some beneficial and others are not as well defined. There is some controversy regarding how much LA is needed from the diet for adequacy. Although LA is needed to synthesize downstream fatty acids, it may lead to increased inflammatory fatty acid production.
Optimal range: 6 - 12.3 Ratio
